Ore is placed in 10 m lifts, and leached with cyanide solution. Pregnant leach solution is clarified, filtered, and de-aerated, then treated with zinc dust to precipitate the precious metals. The precipitated metals are subsequently pressure filtered, and the filter cake smelted to produce doré.
The processing plant consists of a three-stage crushing circuit incorporated with an XRT based mineral sorting system that will reject 40% waste material on average. The mineral sorter concentrate will be blended with the crushing circuit fines to feed a ball mill (6,700 tpd) followed by conventional lead and zinc flotation circuits.
From the late 1880’s to the early 1980s, the “Silver Valley” was the country’s largest producer of silver, lead zinc, and other metals. The mining and ore-processing methods used to extract silver, lead, zinc, and other metals produced large quantities of waste material containing toxic hazardous substances such as cadmium, lead, and zinc.
Cost-effectiveness and operational efficiency will be achieved by a number of factors, including the use of the low-cost open-pit method with a small stripping ratio (shallow horizon), a high content of metals in the ore (5.21% of zinc and 1.15% of lead), and innovative process solutions (eg a floating barge platform-based concentrator, digital

30 Oct 2019 — LME investors favor copper, nickel; shun lead and zinc: survey come amid a supply scramble ever since Indonesias 2014 nickel ore export ban. It is mainly exported as nickel pig iron, production costs of which can now be Bulgaria, Burkina Faso, Burundi, Cambodia, Cameroon, Cape Verde, Cayman
Lead and zinc can be produced pyrometallurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 50-70%, and the sulfur content of sulfidic ores is in

In its 90 years of processing an extensive metallurgical database was compiled, showing that excellent recoveries (averaging 93 percent for zinc, and 92 percent for lead) and good concentrates can
Lead and zinc mining in these areas was by both surface and underground mining methods. Known depths of underground operations range up to 220 feet in depth; other operations may have been deeper. Ore processing was done with a combination of crushers, rollers and hand-operated and steam-operated jigs.
