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.
The greenish powder that remains once the water content of the froth has evaporated is copper concentrate. But it's not pure copper yet, it's a copper iron sulphide, made up of about 35 per cent pure copper. Now, it's ready for smelting. Copper concentrate is fed into the ISASMELT furnace, where it is heated to 1185 degrees Celsius.
Mining Safety. Operating safely is a core value, and our employees embrace a culture where we protect one another every day. We are proud to be recognized nationally for our commitment to metal mining safety. Doe Run and our predecessors have earned the National Mining Association’s Sentinels of Safety award a combined 28 times since 1971.

Zinc processing - Zinc processing - Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or ...
Zinc is a bluish-white metallic chemical element that is ductile in its pure form but in the commercial form it is brittle at room temperature and becomes ductile on slight heating. It occurs amply in minerals and is considered an essential micro nutrient for both plants and animals.

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
