Ore is then removed and hauled to the surface. Generally stoping is used when the copper mining is a byproduct. 20 In a room and pillar operation, first large horizontal drifts (called rooms) are excavated parallel to ...
Roasting (metallurgy)
Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, by froth flotation.

Nickel Laterites: The World's Largest Source of Nickel ...
· Nickel is found in two types of deposits; Nickel laterites and magmatic sulfide deposits. Although nickel Laterites make up 70% of the world's nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world's nickel. In the last 10 years, the production of nickel from magmatic sulfide deposits has slowly decreased and ...
A TGA/DSC Study on the Kinetics of Nickel Laterite Ore ...
"Following the depletion of nickel sulfide ores, laterites are considered as one of the main sources for producing nickel and cobalt. One of the primary steps in pyrometallurgical extraction of nickel from laterites involves partial reduction of the ore at temperatures below 1000°C. Studying the kinetics of laterite reduction provides valuable information on reducibility of nickel laterites ...

「nickel processing from sulfide ores」
Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfiderich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created threatening to poison the nearby water
