The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore apply gravity separation. However, all kinds of Iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation. Herein, magnetic separation and flotation separation will be used.
An estimated 90% to 98% of the cadmium present in zinc ores is recovered in the mining and beneficiating stages of the extraction process. Figure 1 shows a schematic flow of mining and beneficiating a typical leadzinc ore. Figure 1. Schematic flowchart of mining and beneficiating a typical leadzinc ore; Smelting and refining
