SANCOT and the International Tunnelling Association (ITA)

The South African National Committee on Tunnelling (SANCOT) was formed in 1973 during a phase of extensive infrastructure
development in South Africa, in particular the construction of the km long Orange-Fish tunnel. This followed the success of the 1970 TUNCON conference in Durban, after which it was decided that it would be useful to form a body covering the interests of owners, designers, contractors, researchers, and suppliers in the underground construction industry. SANCOT has been active since this time, promoting the use of underground space, exchanging information, and arranging conferences and seminars.

Introduction to our new President...

MAREK DWORZANOWSKI: Marek was born and educated in the United Kingdom. He attended the University of Leeds where he studied Mineral Processing, graduating in July 1980 with a BSc Honours. During 1979 he worked as a vacation student at Hartebeestfontein gold mine in South Africa and decided that on graduation he would start his mining career in South Africa. As it turned out he has spent his entire mining career to date in South Africa. Marek was recruited by Union Corporation, just before it became Gencor, in 1980. He decided that he would not start his career at a gold or coal mine but instead started at Impala Platinum in Rustenburg. His first job was as a concentrator metallurgist at the central mineral processing plant, where he underwent a graduate training programme followed by project work on cyclone classification and flotation reagents.

Report for ITA World Tunnel Congress 2013, February 2013

The South African National Committee on Tunnelling (SANCOT) remains active in promoting tunnelling and the use of underground space. SANCOT functions as a committee within the Southern African Institute of Mining and Metallurgy (SAIMM).

On 3 December 2012 SANCOT held a one day seminar entitled ’South African Tunnelling 2012 – Lessons Learnt on Major Projects’ followed by a half day visit to the Ingula Pumped Storage Project the following day.

PRESIDENTIAL ADDRESS 2013

The role of metallurgy in enhancing beneficiation in the South African mining industry M. Dworzanowski

Beneficiation, in the context of this paper, has two distinct definitions. From an economic perspective beneficiation relates to adding value to a mined raw material as opposed to simply exporting the raw material, in which case other countries will benefit from the value add potential. From a metallurgy perspective beneficiation relates to processes used to upgrade the mined raw material. Clearly then, 'economic beneficiation' is dependent on 'metallurgical beneficiation'. South Africa possesses the world's largest mineral resources by value and is the world's largest producer of many mined commodities.

Diamonds - Source to Use 2013

Re-reading the foreword in the 2010 Diamonds Source to Use Conference proceedings reminded me of the turmoil that the industry was in at that time. Since then, the survivors have dusted themselves off, new allegiances have been forged, and junior mining companies have made significant acquisitions and elevated themselves to the ranks of the majors.

Obituary Ben Alberts

Barend Christaan Alberts suffered a stroke and passed away on Tuesday 8 April, 2013. The mining industry mourns his passing at the age of 74. Known by his younger colleagues as ‘Baas Ben’, he left deep footprints in the development of the South African mining industry, as well as internationally. He was a devout Christian and family man, and together with his wife Ansie and his family we are all blessed to have had the privilege of his life with us.

Obituary Danie Krige - South Africa’s Giant of Geostatistics

Danie Krige - an international household name to anyone who studied or practised the science of evaluating mineral resources for mining purposes, died recently in
Johannesburg.

While his name may not be familiar to many people outside the field, so new and revolutionary were his ideas – applying mathematical statistics to the spatial evaluation of orebodies – that the processes he developed were named after him, becoming known in the industry as ‘kriging’. This technique has helped improve ore evaluation methods and reduce the financial risk of investing in mining projects.

CSMI and Synergy Global - building skills to advance business–community relations

Mounting pressure between businesses and communities in various parts of the world is creating serious social and economic risk, demanding intervention by highly skilled practitioners. A new course offered by the Centre for Sustainability in Mining and Industry at Wits University will hone and expand these vital skills.

While government, business, and labour have come a long way in forging constructive ways of working together, the interface with communities is less well-explored and has seen some violent outbursts in recent years – especially in the extractive industries.

Key find for acid mine drainage on World Water Day

A newly developed membrane used to separate waste from water could become key in the treatment of pollutants ranging from acid mine drainage to oil-containing wastewater, as well as in processes ranging from desalination to kidney dialysis.

The research was published in the prestigious international journal Nature on Friday 22 March, coinciding with World Water Day and falling within South Africa’s National Water Week.

  • Sibanye CEO confident of Lonmin takeover despite cash burn
    Sibanye-Stillwater is confident its planned purchase of Lonmin will go ahead, but the struggling platinum producer must slow its cash burn, the South African firm's chief executive said. Sibanye's £285-million all-share bid to create the world's second largest platinum miner faces hurdles including Lonmin's weak cash position, competition authority approval and the effects of a stronger rand.
  • Talaxis to acquire up to 75% of Mkango’s Songwe project
    Noble Group subsidiary Talaxis has entered into definitive agreements with Mkango Resources to acquire up to a 75% interest in Mkango’s Lancaster Exploration subsidiary, as well as a 49% stake in its downstream metals division Maginito Investments. In January, Talaxis paid Mkango £5-million in return for a 20% stake in Lancaster, which holds the licence for the Songwe Hill rare earths project, in Malawi.
  • Goldstone renews Ghana prospecting licences
    The prospecting licences for Goldstone Resources’ Homase-Akrokeri project, in Ghana, have been extended to April 2020. Goldstone CEO Emma Priestley noted that the company was pleased to have received these renewals, and especially for an extended period.
