General standards for publication in the Journal
To merit consideration for publication, a paper should conform to the high standards that have been established over many years. The paper should contain material on research and scientific items that are new, with interpretations that are novel or of new significance, or conclusions that cast fresh light on old ideas. A paper can incorporate developments that would be of interest to technical people or be of benefit to the industry. A paper should not be a repetition of well-known practices or concepts.
Well-prepared, topical, and original review papers will be considered for publication. Review articles should be comprehensive and indicate worthwhile new advances, new directions for research, and deficiencies in knowledge. A review article merely recording published work without any critical comments and conclusions is not acceptable.
All papers, no matter how technical the subject, should be written with the average professional reader in mind. There should be sufficient background to enable the implications of the work to be readily understood. The amount of textbook material should be kept to the minimum essential to the argument. The length of a paper is not a criterion of its worth, and all submissions should be as brief and concise as possible. Although reference to the names of new products, processes, and services is not restricted, it is the SAIMM’s policy not to allow editorial matter to be used for blatant advertising purposes.
The Journal encourages articles with a Southern African flavour that reflect challenges and opportunities relevant to Southern Africa. This includes current and future technologies, commodities, and operations of importance to the mining and metallurgical sector in the region. Papers from elsewhere presenting global innovations, research and developments applicable to the minerals, mining and metallurgical sector in general would also be considered.
Permission to publish and copyright
Authors are required to sign the Permission to Publish agreement in which the first publication rights for a contribution to be published by the SAIMM are strictly reserved by the Institute. Reproduction of material for non-commercial purposes is permitted, and indeed encouraged, provided that the source is fully acknowledged.
The author is the owner of the copyright in the contribution.
Preparation and submission of contributions
To submit a paper, the Author shall first register as an Author on the SAIMM’s Online Journal System (OJS). Once registered, the Author will be able to submit the paper (in MSWord format) on OJS. In the event of a problem with registering on the OJS, the corresponding author shall contact the Journal coordinator, Ms Kelly Matthee, at firstname.lastname@example.org
Layout and style
The manuscript shall be set for A4-sized (210 mm × 297 mm) paper. Left-hand and right-hand margins should be 20 mm. The manuscript must be prepared in Microsoft Word in 11-point Arial font with 1.5 line spacing. The text shall be left-justified. Pages shall be numbered. The manuscript should not exceed 24 pages, including figures, tables, and references.
Authors shall use UK English, with spelling that conforms to the style of the Oxford English Dictionary. An online dictionary and language reference is available from the Oxford University Press at http://oxforddictionaries.com.
It is recommended that authors who are not proficient in English should use the services of a professional English-language editor prior to submitting their article for technical review. As a JSAIMM partner, Edanz Editing offers a 10% discount on editing services and provides a certificate of compliance to the journal guidelines. Use of a professional editing service does not guarantee publication; this decision remains that of the Publications Committee.
Sections shall not be numbered and shall be kept to a maximum of three levels:
- First level headings are bold
- Second level headings are bold italic
- Third level headings are italicized
Only the first letter of headings is capitalized.
Equations and symbols
Mathematical and chemical equations shall be placed on separate lines, numbered consecutively in square brackets at the right-hand margin. All equations should be set in
Typeface: Cambria Math italic size 12 or Times New Roman italic size 11.
For reactions, the normal text arrow (Equation 1) should be used. Ensure that the correct Word symbols are used for multiplication (×: Alt+0215, not x) and minus (−: Alt+8722, not a hyphen or the n-dash, alt+0150).
Symbols in formulae should be in italics and should be defined at first use in the text. A separate Nomenclature section at the end of the paper, immediately preceding the list of references, should be included if a large number of symbols is used.
Equations should be numbered in right-justified square brackets, and punctuated appropriately if they form part of a sentence:
2ZnS + 3O2 → 2ZnO + 3SO2 
E = 1.23 – 0.06 pH 
E = mc2 
Simple mathematical expressions and sub- and superscripted characters, such as SO42−, are inserted in the text. Do not embed equations as images. Do not use computer code (Fortran, etc.), such as the asterisk * for multiplication or the carat ^ to that indicate that superscripts follow.
The International System of Units (SI) units and symbols shall be employed, as laid down in the SI guide from the US National Institute of Science and Technology (http://physics.nist.gov/cuu/pdf/sp811.pdf).
Where acronyms (e.g., UNO) are used for the first time, the full definition shall be given with the abbreviation in brackets; thereafter, the abbreviation shall be used throughout the text. Abbreviations shall generally be avoided in titles, headings, table and figure captions. Abbreviations should not be used in the Abstract or Keywords.
Use a full stop (period) as the decimal indicator. In accordance with SI convention, numbers greater than 9999 or smaller than 0.0001 shall be separated into groups of three to the left and right of the decimal place, respectively, with a space between the groups as the thousand separator. A comma shall be used as the thousand separator only for financial figures.
Figures and tables
All figures and tables shall be placed at appropriate breaks after they have been cited in the text.
Figures shall be numbered in Arabic numerals and the title shall not be abbreviated—thus, Figure 1, not Fig. 1. Each figure shall be described in a short informative caption. There is no punctuation at the end of a caption. All figures shall be cited in the text before the figure appears.
The style of figures for a particular paper shall be uniform—i.e., typeface of wording, line widths, etc. All lettering and lines shall be of consistent density. The use of a san-serif typeface like Arial is preferable. Figures should contain only essential wording, such as the indication of nature and units on the axes of graphs. Please keep in mind that your figure will be reduced to fit in the most appropriate of the following section column widths of 65, 103, 135, and 175 mm. Lettering should therefore be big enough on the original to be legible on the reduced image.
All figures (including line diagrams, maps, charts, and graphs) should be of good quality, whether in black and white or colour. Figures should not be ‘stretched’ in the horizontal or vertical direction, i.e., they must preserve their original aspect ratio. High-resolution colour or greyscale photographs are acceptable and shall be submitted as EPS or JPEG files and labelled in the same manner as figures.
Tables shall be numbered in Roman numerals, e.g., Table I, Table II, and have a short caption (heading). There is no punctuation at the end of a caption.
The left column of a table should be left-justified. Other columns are typically centre-justified, depending on the content. Decimal points should be aligned in a column. Only the first word of a column or row heading should be capitalized.
A paper should typically consist of an Abstract; Introduction; Theory (if appropriate); Experimental procedure or Methodology; Results; Discussion; Conclusions; Acknowledgements; References. The Results and Discussion can be combined if deemed appropriate. Except for review articles, inclusion of a lengthy literature review should be avoided.
The title should accurately reflect the contents of the submission, with adequate specificity, but not be too wordy. Use of articles (a, an, the) should be avoided where possible. The title should avoid abbreviations, contractions, and acronyms.
Provide only the initials and surnames of the authors. Affiliations shall be indicated by superscript numbers after the names of authors. The corresponding author shall use his/her professional email address of the institution at which the work was carried out.
The ORCID (Open Researcher and Contributor Identification; https://orcid.org/) of all authors shall be included in articles submitted to the journal. Authorship shall conform to the notions of responsibility and credit. The list of authors shall include only individuals who have made a significant contribution to the production of the work at an intellectual, practical, or conceptual level. Examples of criteria to consider include who conceptualized the study, who solicited funding for the study, who carried out the study, who wrote the manuscript, and who supervised the study.
A CRediT author statement should be included with the manuscript submission (see below). CRediT offers authors the opportunity to share an accurate and detailed description of their diverse contributions to the published work.
- The corresponding author is responsible for ensuring that the descriptions are accurate and agreed by all authors
- The role(s) of all authors should be listed, using the relevant categories
- Authors may have contributed in multiple roles
Original signatures of all authors must be included on the Permission to Publish form, stating that all authors agree with the contents of the manuscript and its submission to the Journal.
The Abstract shall not exceed 250 words and shall cover the principal aims and scope of the work: a brief background and reason for the study, the experimental procedure, main results, and summary of findings. The abstract shall not contain abbreviations or references. Provide a list of about six keywords.
Provide details of all funding sources. Do not abbreviate these sources.
