The mine is the largest underground salt mine in the world. It runs more than 500 m deep under Lake Huron and goes into the lake for 7.5 km! See videoclip (2:23). Heap leach mining works well for large volumes of low grade ores, as reduced metallurgical treatment (comminution) of the ore is required in order to extract an equivalent amount of minerals when compared to milling. The significantly reduced processing costs are offset by the reduced yield of usually approximately 60-70%. The amount of overall environmental impact caused by heap leaching is often lower than more traditional techniques. It also requires less energy consu… can labelwriter 4xl polyester void labels
