What you should know about Asa Metals
Small volumes of foundry sand were also produced and supplied to various South Africa and international customers. To assist in delivering the requirements of customers, a laboratory is operated on site. The laboratory is equipped with state of the art analytical instruments to ensure that consistently high quality product is produced. Samples are analysed by a variety of techniques including wet chemical methods, ICP and automatic absorption. All of the final product sold is analysed and the full specifications are forwarded to the client with every order dispatched. Chromite ore is mined along the eastern and western rims of the complex. Chromite is the only source of chromium and is predominantly used for the production of ferro-alloys and chemicals. World production of chromite ore is around 14 million tons with the South African market share accounting for around 39%. These seams are remarkable consistent throughout the BIC in both physical and chemical nature. The lower of the two seams is known as the LG6 (lower group 6) seam and is approximately 1,1 to 1,3 metres thick. The ore is drilled and blasted before being scraped mechanically to loading points from where it is transported to the shaft tips in locomotive pulled hoppers. Run of mine ore is further beneficiated on surface through a series of size classification and density separation steps that allows for efficient separation and removal of pyroxenite waste from the chromite. Foundry sand produced during the on surface beneficiation is stockpiled separately for supply to international customers while lumpy chromite and metallurgical concentrates are transported to the on site smelter for further beneficiation. Electrical energy, required for the chemical reactions to occur, is supplied to the submerged arc furnaces, through Söderberg electrodes.
