Question

Mangampeta is one of the largest reserves of _____________- mineral in the world.
(A) Aluminum
(B) Iron ore
(C) Barytes
(D) Coal

Answer 1

Hint: It is a mineral comprising barium sulfate (BaSO4). Baryte is by and large white or dull, and is the fundamental wellspring of the component barium. The baryte bunch consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate).

Complete answer:
 Mangampeta is in the YSR Kadapa locale and has perhaps the biggest save of barytes mineral on the planet. The barytes saves were found in 1960 and it has been mined since 1967.
The emanating structure, here and there alluded to as Bologna Stone, achieved some reputation among chemists for the glowing examples found in the seventeenth century close to Bologna by Vincenzo Casciarolo.
The American Petroleum Institute determination API 13/ISO 13500, which administers baryte for penetrating purposes, doesn't allude to a particular mineral, but instead a material that meets that detail. Practically speaking, notwithstanding, this is typically the mineral barite.
The expression "essential barytes" alludes to the principal attractive item, which incorporates rough baryte (run of mine) and the results of basic beneficiation techniques, for example, washing, jigging, hefty media detachment, postponing, buoyancy. Most unrefined baryte requires some moving up to least virtue or thickness. Baryte that is utilized as a total in a "hefty" concrete is squashed and screened to a uniform size. Most barite is ground to a little, uniform size before it is utilized as a filler or extender, an expansion to modern items, in the creation of barium synthetic substances, or a weighting specialist in oil well penetrating mud.
The name barite is gotten from the Ancient Greek: βαρύς, romanized: barús, 'weighty'. The American spelling is barite. The International Mineralogical Association at first embraced "barite" as the official spelling, yet suggested receiving the more seasoned "baryte" spelling later. This move was disputable and was prominently overlooked by American mineralogists.

Thus, option (C) is the correct answer.

Note: Baryte happens in numerous depositional conditions, and is saved through numerous cycles including biogenic, aqueous, and vanishing, among others. Baryte normally happens in lead-zinc veins in limestones, in underground aquifer stores, and with hematite minerals. It is frequently connected with the minerals anglesite and celestine. It has additionally been distinguished in shooting stars.
