Mineral processing | metallurgy | Britannica

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

Flux (metallurgy) - Wikipedia

In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were carbonate of soda, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.

Fire Assay Procedure - Mineral Processing & Metallurgy

“Mineral processing is the first step in the solid mineral extractive process. The goal is to produce granular mate-rial which meets a specific set of requirements in terms of material composition and physical characteristics (espe- cially granulation). The minerals are then used either as is (e.g. potassium fertilizer, coal) or they pass through ad-ditional processing stages (metallurgy ...

Flux | metallurgy | Britannica

Flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite.

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century. It has been described as "the single most important operation used for the ...

11.18 Mineral Wool Manufacturing - US EPA

11.18 Mineral Wool Manufacturing 11.18.1 General1,2 Mineral wool often is defined as any fibrous glassy substance made from minerals (typically natural rock materials such as basalt or diabase) or mineral products such as slag and glass. Because glass wool production is covered separately in AP-42 (Section 11.13), this section deals only with the production of mineral wool from natural rock ...

Vanadium processing | Britannica

Vanadium processing, preparation of the metal for use in various products.. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926° C (3,499° F). The metal is used principally as an alloying addition to high-strength low-alloy (HSLA) steels and, to a lesser extent, in tool steels and iron and steel castings.

High-frequency vibrating screens - Wikipedia

High frequency vibrating screens are the most important screening machines primarily utilised in the mineral processing industry. They are used to separate feeds containing solid and crushed ores down to approximately 200μm in size, and are applicable to both perfectly wetted and dried feed. The frequency of the screen is mainly controlled by an electromagnetic vibrator which is mounted above ...
