Hint:We will discuss mining.There are four main methods of mining which include underground, surface, placer and in-situ. The method used for mining depends upon the kind of resource that has been targeted for extraction, the deposit location and capacity of each method to extract the resource.
Baryte is a mineral consisting of Barium sulphate, generally white or colourless in colour and it is the main source of element barium.
The name baryte is derived from the ancient Greek word barus which means heavy. It occurs mainly in the environment deposit including biogenic, hydrothermal and evaporation.It commonly occurs in Lead and zinc in limestone in hot springs mainly associated with deposits of hematite Ore. They are associated with minerals like celestine and anglesite. It has also been identified in meteoroids. The deposits are found in Australia, Brazil, Nigeria, Canada, India and Pakistan. Baryte is used in oil and gas drilling. Mangampeta is located in YSR district. It has one of the largest reserves of barytes minerals in the world. These reserves were discovered in nineteen hundred and sixty.
Hence, the correct answer is option (A).
Note:People mine because they need minerals to construct roads and hospitals, to build automobiles and houses, to make computers and satellites, to generate electricity and Other goods for daily use. mining includes extraction of minerals and metals like coal Diamond Gold Silver. It is done by scrapping soil from top of ground and it is called surface mining.
