Extractive metallurgy Wikipedia

Extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. The field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for direct

What are the main methods of mining? American

There are four main mining methods underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Flotation Mineral Processing Metallurgy

Jan 11, · The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

Mining Methods 101 How the Metals We Need Are Extracted

Jul 06, · Before that can happen, however, the ores must be excavated from the ground. Typically, this is done through two basic techniques subsurface (underground) and surface mining. Surface mining is both the less expensive of the two and the goto method when the desired minerals are located near the surface of the Earth.

extraction of metals introduction
