pagesJournal Comment

A monthly publication devoted to scientific transactions and specialist technical topics is unlikely to be on the priority reading list of the majority of the mining and metallurgical community. But it is the ambition of the Publication's Committee to make the Journal of much wider interest to our general membership from technician trainees to mine managers to CEO's of our constituent companies. It is to entice general readership that some 1200 words of valuable space are devoted to the Journal Comment each month. This is intended to highlight some of the features and impact of the papers to excite and activate attention.

To entice this preliminary glance before confining the publication to the book shelf or even the wpb, the author has to call on a large measure of journalistic licence in style, titles and quotations. It is essential to be spicy, controversial and even provocative to separate it from the abbreviated authoritative but necessary scientific style of the bulk of the contents.
The Journal Comment aims to be an enticement to dig into some important feature of the papers in the issue. For this reason it has been decided to include it as a separate item on the Institutes Web Site. This might provoke those who enjoy twittering, blogging and googling to submit comment and criticism, all of which will be welcomed and responded to. At least it is proof that somebody has read it.

Mine Planning and Equipment Selection (MPES 2015)

The Southern African Institute of Mining and Metallurgy (SAIMM) hosted the 23rd International Symposium on Mine Planning and Equipment Selection (MPES 2015) at the Sandton Convention Centre in Johannesburg from 9 to 11 November 2015. This was the first time that South Africa has hosted the MPES in its 25-year history. This conference’s theme was ‘Smart Innovation in Mining’ in order to recognize technological innovations and new ideas that are required to prepare the industry for the mine of the future.

Furnace Tapping 2014

Furnace Tapping 2014 was the first event of its kind, focusing on the challenges associated with the tapping of furnaces and ways in which these challenges are currently addressed. The conference was inspired by an in-house event arranged by Dr Lloyd Nelson – then employed by Hatch Africa – in 2003, and the need for peer-reviewed papers published in the open literature. This was identified when I conducting a literature survey for my PhD studies, which focused on enhancing the taphole design for silicomanganese furnaces.

The School of Chemical and Metallurgical Engineering at the University of the Witwatersrand

Celebrating one’s 21 year of existence is indeed a most joyous occasion, and another milestone in the history of Chemical and Metallurgical Engineering at the University of the Witwatersrand. Since its formation in 1995 through the merger of the departments of Chemical Engineering and Metallurgy and Materials Engineering as the School of Process and Materials Engineering, the School has gone from strength to strength. In 2005 ‘Chemical and Metallurgical Engineering’ became the official designation of the School after ratification of the name change by the University Council. The School has been at the forefront of education and research in engineering and has contributed greatly to the demand for skilled manpower by the process, beneficiation, and metallurgical industries in South Africa. The School prides itself on its contribution in terms of human resources training and development, knowledge generation, and community involvement and contributions. A significant number of industry and academic leaders locally and worldwide are Wits Chemical and Metallurgical Engineering graduates and alumni.

Surface Mining September 2014

Two years have passed since the last Surface Mining Conference was held. At that time, optimism prevailed and the spectre of the Global Financial Crisis (GFC) had blown away. Commodity prices were cresting a wave created from continued industrial expansion in China, and the mining industry looked set to right its floundering course on a global scale. Explorers and developers on the world’s stock exchanges, whether juniors or majors, thrived and impressive joint ventures, mergers, and acquisitions were the order of the day.

Nuclear Materials

This special edition of the Journal of the Southern African Institute of Mining and Metallurgy is dedicated to the Nuclear Materials Development Network (NMDN) of the Advanced Metals Initiative (AMI) of South Africa’s Department of Science and Technology (DST). The AMI consists of four networks: the Light Metals Development Network (LMDN) which is coordinated by the CSIR, the Precious Metals Development Network (PMDN) and the Ferrous Metals Development Network, both coordinated by Mintek, and the NMDN which is coordinated by the South African Nuclear Energy Corporation SOC Ltd (Necsa).

Platinum In The 21st Century

‘There is a tide in the affairs of men’ ... Shakespeare

The theme of most of my previous Journal Comments has been job creation. This demands identifying the goods and services for sale, and its corollary, the skills and education required.

On this latter score, the mining professional community has had some spectacular success in the 21st century. Many hundreds of skilled mining engineering graduates and diplomates have been produced using the latest in computer-based education, a good percentage being women.

Heaping coals of fire upon our heads

A blessing at the best of times, electricity has become the bane of life in South Africa: it adds quality to life, but when supply is erratic, as we all know too well, the effects cripple and evoke anger. Constraints in the supply of electricity are damaging the economy. Some predictions even foretell a crisis of monumental proportions. Eskom can barely meet current demand.

Conference ’Platinum – Metal for the Future’

The SAIMM biannual platinum conference was first convened in 2004 and has run regularly through to 2014. During this period the industry has moved through a number of challenges – from the global financial crisis to metal pricing spikes and troughs, labour unrest in the form of a crippling five-month strike in South Africa in the first half of 2014, and now sustained oversupply in the face of reduced demand associated with the slow recovery of the European markets and the cooling of the Chinese economy.

Pyrometallurgical modelling

’It is unworthy of excellent men to lose hours like slaves in the labour of calculation which could safely be relegated to anyone else if machines were used.’
– Gottfried Wilhelm Leibniz (1646 - 1716)

’The computer is incredibly fast, accurate, and stupid. Man is unbelievably slow, inaccurate, and brilliant. The marriage of the two is a force beyond calculation.’
– Leo Cherne (1912-1999)

Pyrometallurgical operations are essentially concerned with the high-temperature processing of materials. These chemical processes can be extremely complex, involving reactions between gas, solids, liquid slag, and liquid metal (and sometimes other phases as well).

Young Professionals

As part of its commitment to supporting young professionals entering the mining and metallurgical industries, the SAIMM holds a Student Colloquium every year. The ten papers in this edition of the Journal are based on presentations made at that event by students and recent graduates in mining engineering, metallurgy, and minerals processing.
