Lead - Essential Chemical Industry

The lead ore concentrate from the flotation tanks now contains about 50% lead and ca 0.1% of silver, a relatively small but valuable amount. (b) Smelting Smelting is usually a two-stage process as described here, although single-stage methods with lower energy use and emissions are also used.

Experimental Study on Flotation Process Conditions of Lead ...

On the basis of analyzing sample properties of lead-zinc ore, the optimum experimental condition combination was obtained from systematic experimental studies of the conditions. The experimental condition combination was validated by the full process closed-circuit experiment, which showed that the good separation indexes on lead grade of 59.78% in lead concentrates, the lead recovery of 87.50 ...

Electric Smelting Furnace of Ore

05/05/2017· Eventually, the lead-zinc alloy was liquated and yielded refined zinc slabs and lead pigs, also an iron-silver-copper cake that was sold. The power consumption, calculated back to the original zinc ore from Burma, was 860 kw.-hr. per ton. The total consumption per metric ton of 57 percent material on the three furnaces was 3,335 kw.-hr., or ...
