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.
The lead concentrate by weight was obtained to be 81.80, confirmed being of high economic grade having surpassed 60 wt Pb element in an ore. It is hoped that this will enhance its development to meet both local and international de-mand for potential investment opportunities.

Garpenberg Fig. 17 is considered the most productive zinc underground mine in the world. In 2017, the mine output was 2.63 Mta of ore, with lead, copper, gold and silver being produced in addition to zinc. The Tara Mine in Ireland is Europes largest zinc mine. The ore is extracted there from a depth of about 1000 m Fig. 18.
Aug 28, 2014 The most common lead- and zinc-containing ores are galena and sphalerite. A lead-zinc ore may also contain gold and silver, lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. Lead and zinc ores are mined primarily underground in countries including China, Australia, Canada, the Unites States, and Peru.

With the rising gold prices in recent years, it further stimulated the rapid development of gold industry. As the exhaustion of high-grade gold ore, researching on middle-low grade and refractory gold ore and strengthen the traditional gold mining process undoubtedly have become the main trend in global gold beneficiation industry.
With the exhausting of leadzinc sulphide ores, the recovery of lead-zinc oxide ores becomes more and more significant. Extensive work has been carried out at home and abroad on the treatment of lead and zinc oxide ores in reagent scheme, flotation flowsheets, and joint process. Sliming is one of the main reasons why the lead-zinc oxides are difficult to recover.
