Lime products play a key role in the mining and extraction of non-ferrous metals, including aluminum, copper, gold, nickel, cobalt, uranium, titanium and lithium. Lime is also important for the pyrometallurgical refining and smelting of several non-ferrous metals. In addition, lime products are used in effluent and tailings treatment, and in settling, dewatering, filtration,

Read MoreBecause the hydromet process used at Long Harbour eliminates the requirement for smelting concentrate, it has an economic advantage over the traditional two-step smelting and refining process. The process will also yield more of the valuable cobalt which is lost to a great extent in the smelting process.
Read MoreBasic to any consideration of matte refining are the contents of iron and sulphur. In general, matte will have much loss iron and much less sulphur than concentrate, for an equivalent weight of nickel, copper or cobalt. The process of smelting to produce matte rejects a large proportion of the iron, and the sulphur associated with it.
