Together with the metals zinc and lead, chlorides (of sodium and potassium) and fluorides vaporize in pyrometallurgical processes; consequently, for instance, when crude zinc oxide is produced it contains most of the zinc, lead and halides from the furnace load, along with minor amounts of other materials pneumatically conveyed from the furnace.

Uses of Zinc | Supply, Demand, Production, Resources

Zinc is commonly found in mineral deposits along with other base metals, such as copper and lead. Zinc deposits are broadly classified on the basis of how they are formed. Zinc is produced mainly from three types of deposits: sedimentary exhalative (Sedex), Mississippi Valley type (MVT), and volcanogenic massive sulfide (VMS).

Zinc: smelting, producing and classification-Metalpedia

The zinc is scrubbed from the vapour in the condenser via liquid lead. The liquid zinc is separated from the lead in the cooling circuit. Approximately 5,000 metric tons (5,500 short tons) of lead are required each year for this process, however this process recovers 25% more lead from the starting ores than other processes.

6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.

A Novel Technology for Separating Copper, Lead and Zinc in ...

In this work, oxidizing roasting was combined with leaching to separate copper, lead, and zinc from a concentrate obtained by bulk flotation of a low-grade ore sourced from the Jiama mining area of Tibet. The flotation concentrate contained 7.79% Cu, 22.00% Pb, 4.81% Zn, 8.24% S, and 12.15% CaO; copper sulfide accounted for 76.97% of the copper, lead sulfide for 25.55% of the lead, and zinc ...
