What is a mineral in mining?

Mining is the process of extracting useful minerals from the Earth's surface, including the seas. A mineral, in the context of mining, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure.

What is placer mining?

This mining method exploits unconsolidated minerals mixed with sediments. Rinsing and sifting are commonly employed to remove resources from mixtures. Similar to gold panning, most placer mining operations are conducted in sandy areas and riverbeds where mineral deposits are located.

What is the difference between a deep gold mine and a foreign mine?

These issues are further detailed below. Foreign deep mines mostly utilize downward filling mining and the empty field subsequent filling method. However, most mines in China employ the upward subsequent filling mining method, while deep gold mines mainly use the approach-type filling mining method.

What is in-situ mining?

This method differs from both underground and surface mining as it does not extract the ore and rock mix for processing at the surface of the mine. In-situ mining involves using chemical solutions to dissolve the minerals and pump the pregnant solution/solution containing dissolved minerals out of the mine for processing.

Why is mining important?

Mining has been a cornerstone of global economic activities for millennia, evolving from basic surface extraction to complex underground and quarrying operations. Today, it plays a vital role in industries like electronics and renewable energy, supplying essential resources for technological advancement.

Which mining companies are planning to build intelligent mines?

Leading mining enterprises such as China Gold, Shandong Gold, and Minmetals Group are planning to construct intelligent mines. Meanwhile, Hongling and Prang Copper Mining are investing in remote control mining equipment, contributing to the overall progress.
