Silver, lead and zinc are extracted from the ore using grinding, sequential flotation and leaching techniques that produce high-grade, marketable lead and zinc concentrates with a high silver content.
Silver-containing lead-zinc ore: The silver, lead, and zinc in the ore can all be recovered and are the main mineral raw materials for producing silver. Use the flotation method to …
Domestic lead mine production for 1991 totaled 480,000 megagrams (Mg) (530,000 tons) of lead in ore concentrates, a decrease of some 15,000 Mg (16,500 tons) from 1990 production. Except for mines in Missouri, lead ore is closely interrelated with zinc and silver. Lead ores from Missouri mines are primarily associated with zinc and copper.
During the year ending FY20, Cannington mined 2,792 thousand wet metric tonnes (kwmt) of ore grading 156g/t silver, 4.7% lead and 3.3% zinc. Payable metal production was 11,792 thousand ounces (koz) of silver, 110.4 thousand tonnes (kt) of lead and 66.7kt of zinc.

Discover insights into why silver is found with lead and zinc, including geology, mining implications, and the impact on their operations.
Abstract A solid waste from zinc production, zinc plant residue (ZPR) is a valuable resource for the recovery of zinc (Zn), lead (Pb), and silver (Ag). However, the ferritic structure of ZPR makes it difficult to leach these metals. Here, in order to increase the reactivity of the ZPR, mechanical activation using a high-energy ball mill was used. …
