application of the zinc cementation process at the Homestake Mine in Lead South Dakota in 1897 (Mular, 2002). Zinc cementation was initially performed using long sloping boxes filled with bundles of coarse zinc shavings. Gold bearing solutions were passed through sand filters to remove suspended solids and then through the zinc boxes for metal ...

The leadzinc ore is a typical lowgrade complex polymetallic sulphide ore. Its typical mineralogy is characterized by a high content of cryptocrystalline graphite, low content of lead, zinc, and copper, and fine grain size. However, the aggregation size of sulfide mineral aggregations is coarse, and the symbiotic relationship is relatively simple. Conventional process treatment requires the ...

Tables 32 and 33 can therefore only be regarded as approximations. Table 32 gives the cost of the straightforward treatment in airlift machines of a simple ore such as one containing easily floated sulphide copper minerals, and Table 33 that of the twostage selective flotation of a leadzinc or similar complex ore.

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.

In the beneficiation process, the sulfide leadzinc ore is mainly flotation. Among them, the proportion of zinc ore in most leadzinc ore is higher than that of lead ore. Therefore, in the actual process, the method of "suppressing zinc and floating lead" is generally adopted. Main principles to deal with leadzinc sulfide ore.
