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 copper-lead-zinc ore dressing plant in sweden with the daily output of 1000t, copper content of 0.58%, lead content of 2.85% and zinc content 4.90%; xinhai adopted copper-lead mixed flotation. final copper concentrate contains copper 20.25% and lead 6.75%, and the lead concentrate contains lead 58.73% and copper 3.40%.

Another private sector company jhagadia copper ltd also produces copper based on secondary 3.2 lead & zinc: it is estimated that the country‟s identified zinc-lead resources as on 1st april 2011 are 671 million tonnes containing 37 million tonnes of zinc and 11 million tonnes of lead metal.

sulphide ore of lead and zinc containing considerable silver was submitted for testing with the purpose of determining a flowsheet for the production of separate lead and zinc concentrates for marketing at their respective smelters. it is necessary to recover as much silver as possible in the lead concentrate as a higher return for this silver is realized than for the silver in the zinc .

the lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. a further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper (16 pounds per ton) or more.

tests have indicated that the recovery of lead from intermediate products into lead bullion and matte is about 83-85% and 13-14% respectively (the total recovery is 97-98%), while copper recovery into the matte and zinc recovery into the slag is 90-92% and 95-96% respectively.

several minerals were only exploited for export, because, apart from copper, there were no smelting or refinery facilities in iran. however, these mines were sensitive to changes in the world market ; when prices of chromite, lead, and zinc dropped in 1960-62, their output also was decreased.

Lead and zinc ore are common symbiotic associated minerals, they often appear at the same time. lead-zinc ore is the main ore for refining lead and zinc metal. it is the main technical process to refine lead first and then zinc in the lead-zinc ore beneficiation. zinc and lead mineral processing flow:.
