Comprehensive Guide for Beneficiation of Iron Ore

2019-10-23    Xinhai     Views(13812)

There are a variety of iron ores in nature, mainly including magnetite, haematite, limonite, siderite, so the beneficiation of iron ore needs the suitable process to improve the economic benefit. The beneficiation of iron ore needs a series of process, including crushing, grinding, magnetic separation, flotation, gravity separation.

What is Cyanidation Gold Extraction Process?

2019-08-26    Xinhai     Views(14394)

Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main gold extraction processes due to its high recovery rate, high adaptability to ore and local production.

    Pyrite Activation in the Lead-Zinc Tailings Recovery

    Xinhai     Views (3994)

    Most non – ferrous metals are metal sulfides ores, such as lead-zinc ore, copper sulfide, which often coexist with a large number of pyrites. Pyrite is the main raw material for industrial sulfuric acid, but China is a leading manufacturer and consumer of sulfuric acid, so the comprehensive utilization of pyrite plays an important role in lead-zinc tailings recovery.

    Copper Ore Dressing Process

    Xinhai     Views (3987)

    Copper ore refers to the mineral aggregate with a certain content of copper ore and can be recycled at the present stage. In general, copper ore is occurred in ore inside as sulfide, and associated with a certain amount of lead and zinc ore.

    Copper Sulphide Ore Flotation Process

    Xinhai     Views (3230)

    The common copper sulfide minerals mainly include chalcocite, covellite, bornite, copper pyrites and tennantite, and their inherent floatability decrease in turn. Copper sulfide ore has better floatability than sphalerite, pyrite and other sulphide, so it is more likely to float from the pulp by adsorpting collecting agent.

    How to Choose Copper Ore Manufacturer?

    Xinhai     Views (2933)

    Copper ore is a kind of high-grade sandy copper ore concentrate. It is widely used in casting, forging, metallurgy, paving, heat treatment, steel structure, space truss structure, ships, bridges, mines and so on

    Copper Sulfide Ore Flotation Technologies

    Xinhai     Views (4261)

    Copper sulfide ore has good inherent floatability, so flotation process is a mature method used for copper sulfide ore separation. In recent years, with the continuous development of copper sulphide flotation technology, many scholars also proposed a series of new principles of mineral processing, such as “collect early, loss early” and “more crushing and less grinding”.

    Crusher for Molybdenum

    Xinhai     Views (2989)

    Molybdenum is widely used in steel, mechanical, electron and aerospace for its high melting point and good solidity. Molybdenum has a low grade of raw material (often is 0.01~0.4%), while high grade is demand in melting, so crushing is necessary.
