1.1.4 Disposal of overburden and waste rock In almost every project, metallic ores are buried under a layer of ordinary soil or rock (called ‘overburden’ or ‘waste rock’) that must be moved or excavated to allow access to the metallic ore deposit. For most mining projects, the quantity of overburden generated by mining is enormous.Iron Ore. Efficiently remove silica and alumina contamination to increase efficiencies in steel production. Our iron ore wet processing plants are proven to successfully deal with silica and alumina contamination in the iron ore, resulting in an increase in the Fe value of the iron ore thereby increasing the efficiency of the steel production process.

Surface mines, on the other hand, usually generate more than twice as much overburden and waste rock as ore. As an example, for underground copper, gold, silver, and uranium mines in the United States, the ratio of overburden and waste rock to ore, is on the order of 0.1:1 to 0.3:1.Feb 02, 2021 Historically, contaminated soil would be transported off the island where it would be destined for landfill.H owever, with the right technology, this material can be processed to remove contaminants, extract value, and return land to good use to meet the growing demands of urbani s ation.
