What is this in mining?

Gangue is a substance that must be extracted along with the required minerals or ores due to their close connection. These materials are usually removed along with target minerals or ores and must then be separated. Gangue can then be thrown out like tails. In some cases there may be other use of materials present in the tail. If such situations occur, the fates can be further processed to remove newly valuable materials.

During the mining process, the materials that appear, usually classified into two groups. Economic fraction is a desirable material that is of value, while an uneconomical fraction, otherwise known as gangue, is everything else. Determining whether mining operations will be economically viable, the costs of the economic fraction department from unnecessary gang are usually considered. Sometimes the desired material will be so integrated with unnecessary gangue that it would be too expensive to extract.

MV of the years has developed ining technology and wereCreated more sophisticated methods for separating economic and uneconomical fractions. Early mining operations could be ineffective and often left a relatively large number of useful minerals in the lower ends. This was often due to the poor ability of older techniques to effectively separate useful minerals from the gang, or the result of minerals that have been suspended in particularly difficult configurations. When new techniques are created, dumps of old tails are sometimes revised for their shops of useful minerals and ores.

Taillings can also be re -examined if new uses appear for old materials. Arsenopyrite was once considered to be unnecessary gang minerals and thrown into the tail as part of an uneconomical fraction. The later development led to the fact that Arsen became a popular insecticide, containing arsenopyrite of mining tail can be considered an economic fraction. When the development occurs like jE This is often redesigned to extract newly required minerals and ores.

In certain mining operations, the gang may contain hazardous materials. This may be the result of mining of hazardous materials, some of which always end up in fate due to processing that is not absolutely effective. In the processing of minerals such as gold and silver, dangerous or poisonous chemicals such as cyanide can also be used in the tail. When this happens, mining operations will often include an environmentally safe landfill to maintain poisonous or dangerous materials present in the fate of the leech out into the groundwater.
