Converting And Casting Process Mining

This process also keeps the lead from oxidizing. The molten lead flows from the blast furnace into holding pots. Lead may be mixed with alloys, including antimony, tin, arsenic, copper and nickel. It is then cast into ingots. Lead exposure. Humans have been smelting lead for thousands of years, poisoning themselves in the process.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.

Metal Casting. In relation to metalworking, casting is the process in which metal is liquefied and poured into a mold which is then cooled and solidified into the shape of the mold’s cavity. The solidified piece of metal also referred to as the casting or ingot is then released from the mold to complete the process.
