Steel making contributes 6% of global CO2 emission (including associated power emissions). Blast furnaces dominate global production, have long capital lives, and resist adoption of decarbonization technology. Deep decarbonization and net-zero production will require both asset replacement from BF to DRI+EAF and development …

Decarbonizing steel production, which generates about 7% of global CO 2 emissions, is a vital step toward achieving a net-zero world. For mining companies that supply the iron ore needed to produce steel, helping steelmakers reach this goal could remedy their own emissions problems.. Many iron ore mining companies are already …

The pressure on the steel industry to reduce its carbon footprint has led to discussions to replace coke as the main reductant for iron ore and turn to natural gas, bio-syngas or hydrogen. Such a major transition from the blast furnace-basic oxygen furnace route, to the direct reduction-electric arc furnace route, for steel production would …

The grind of the final product in this area of South Africa has a large influence on the overall gold recovery. The closer the maximum ore particle size is to the maximum grain size of the valuable material, the more efficient the extraction will be (Stanley, 1987).In the case of these ores, the average grain size of the gold is 75. μm.. Mponeng has a …

The mineral used as media is recycled magnetically. This method is widely used for coal and to remove shale from construction aggregates. Early work has been done to develop a low-cost, effective, safe, and environmentally acceptable "true" heavy fluid but has not led to a commercial success (Khalafalla and Reimers, 1981).
