Mining is the extraction of valuable geological materials and minerals from the surface of the Earth.

Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining.

Once the mineral is extracted, it is often then processed. The science of extractive metallurgy is a specialized area in the science of metallurgy that studies the extraction of valuable metals from their ores, especially through chemical or mechanical means.

Since most metals are present in ores as oxides or sulfides, the metal needs to be reduced to its metallic form. This can be accomplished through chemical means such as smelting or through electrolytic reduction.

Mining valves play a vital role in modern mining production

Mining valves are a type of equipment installed on pipelines to control the flow, pressure and direction of pipelines. Mining valves are widely used in floatings, filling，tailings pond, waterway control, power and long distance pipelines occations. In coal mining, metal mining, petrochemical and other industries, mining valves are often used in fluid delivery pipelines, regulation and control systems. Due to the harsh production environment of the mining industry, mining valves need to have the characteristics of wear resistance, corrosion resistance, and good sealing to ensure the normal operation and safe production of equipment.

In the mining industry, valves are widely used, which can help mines achieve control and regulation of fluid flow, pressure, temperature and other parameters, while ensuring the safety of workers and equipment. Therefore, in mining equipment, process flow and production process, it is crucial to choose the right valve. Only by choosing the right valve can the safe operation of mining equipment and the efficient and stable production process be guaranteed.
