Results for tag: "Gangue"

Gangue is a type of rock found in association with ore deposits. It is composed of minerals that are not of economic value, and is typically found in the form of quartz, calcite, or clay. Gangue is a by-product of the mining process, and is usually discarded as waste. It is sometimes used in the production of construction materials, such as bricks and tiles. Gangue is an important part of the metals and minerals industry, as it is used to separate ore from the waste rock. This process is known as beneficiation, and is used to increase the concentration of valuable minerals in the ore. The gangue is then discarded, while the ore is processed further to extract the valuable metals and minerals. The gangue market is comprised of companies that specialize in the extraction and processing of gangue. These companies are involved in the mining and beneficiation of ore, as well as the production of construction materials. Examples of companies in the gangue market include Rio Tinto, BHP Billiton, and Anglo American. Show Less Read more
