what is mining? what are the different kinds of mining​

Answer 1

Answer:

Mining is the extraction of minerals and elements of economic interest from the earth's surface. As the demand for natural resources increases, the amount of material in mineral deposits decreases. An increase in price of these materials allows companies to continue to profit from mining deposits with lower ore grades.There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit's location below or on the Earth's surface and the capacity of each method to profitably extract the resource.
