What Is Nickel Smelting? (with picture) - Info Bloom

Alex Newth Nickel ore must melt until it becomes a product known as liquid matte, which is usually around 45 percent nickel. Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which ...

Nickel smelting and refining: A long road ahead for Indonesia

May 13, 2015 · When Indonesia placed export restrictions on nickel ore early last year, the plan was to encourage the country’s mining firms to develop their own smelting and processing facilities so that Indonesia could export refined ores and concentrates, which are worth more in the market than raw ones. More than a year later, Indonesia’s ban on ore exports is stimulating investment in processing ...

cobalt processing | Uses, Supply, & Facts | Britannica

In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation from solution, usually as a cobaltic hydroxide. But even in nickel smelting, cobalt starts to oxidize before the nickel and can be recovered from the final converter slag. In the ammonia pressure leaching of nickel, cobalt is ...

The world nickel resources are divided into two major categories, sulphide ore and oxidised ore (laterite ore). The conventional exploitation of nickel sulphide ore is essentially a pyrometallurgical process, where the mined ore is then finely ground, and the nickel sulphide minerals concentrated by froth flotation to produce a nickel concentrate.

12.3 Primary Copper Smelting

A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.
