What is benefaction of ore?

The process of removal of the gangue from Ore is known as Concentration or Dressing or Benefaction. There are numerous methods of concentration and the methods are chosen based on the properties of the ore.

Which term is a product of ore processing that includes a specific ore mineral separated from the rest of the rock?

Other sulphide minerals are commonly present within the ore, especially pyrite. When ore is processed (typically very close to the mine), it is ground to a fine powder and the ore minerals are physically separated from the rest of the rock to make a concentrate. The rest of the rock is known as tailings.

What is the term for ore that has been concentrated by wind or water?

Aggregates. Minerals concentrated by wind and water movement into surface deposits. Placer deposits.

What is a concentration of minerals called?

Ore minerals tend to be concentrated in small, localized rock masses that form as a result of special geologic processes, and such local concentrations are called mineral deposits. …

What is meant by the term concentration of the ore describe various methods used for the purpose?

1 Comment / Chemistry / By Supriya N. The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step.

What is meant by beneficiation process?

From Wikipedia, the free encyclopedia. In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings).

What is meant by the term metallurgy?

metallurgy, art and science of extracting metals from their ores and modifying the metals for use. It also concerns the chemical, physical, and atomic properties and structures of metals and the principles whereby metals are combined to form alloys.

What is called gangue?

In mining, gangue (/ɡæŋ/) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is a necessary, and often significant, aspect of mining.

What do you call the process when ore minerals are created deposited?

Sedimentary or surficial processes (exogenous) The physical processes of ore deposit formation in the surficial realm include; erosion. deposition by sedimentary processes, including winnowing, density separation (e.g.; gold placers)

What is concentrate in mining?

Ore concentrate, dressed ore or simply concentrate is the product generally produced by metal ore mines. The raw ore is usually ground finely in various comminution operations and gangue (waste) is removed, thus concentrating the metal component.

What do you call the process when ore minerals are created?

Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. Ore bodies are formed by a variety of geological processes generally referred to as ore genesis.

What do you call the process when ore minerals are created or deposited?

Lateral secretion: Ore deposits formed by lateral secretion are formed by metamorphic reactions during shearing, which liberate mineral constituents such as quartz, sulfides, gold, carbonates, and oxides from deforming rocks, and focus these constituents into zones of reduced pressure or dilation such as faults.
