Hydrometallurgical copper recovery can be conveniently considered in two stages: theleaching stage, in which the various forms of copper in the ore are placed into anaqueous solution, and the recovery stage, wheredissolved copperis recovered as solid, nearlypure copper metal ready for fabrication or final smelting.Get a Quote
Pyrometallurgical processes resulted in the formation of approximately 3.4 t of SO 2 for every 1 t of copper. The hydrometallurgical process includedpressure leaching under slightly oxidising conditionsindiluted sulphuric acid(at 80–105 °C and 140-350 kPa oxygen pressure). This enabled selective extraction of up to 97% of copper, with less than 10% of pyrite taking part in the reaction.Get Price
Recovering Copper Metal from Leach Liquors. There have been many processes brought out for removing copper from solutions containing that metal, and some of these may find application in special cases, but there are only two which have met with extended commercial use—precipitation by means of metallic iron, and deposition by the electric current.Get Price

The invention relates to amethodfor producingcopperin ahydrometallurgical processfromcopper-bearing raw materials, such as sulfidic concentrates. The concentrate is leached in a leaching stage of several steps into a chloride-based solution. Thecopper-bearing solution obtained from this leaching is subjected to reduction and solution purification, whereafter thecoppercontained in the ...Get Price

In recent years, the principle and theory behind solvent extraction has gained wide acceptance as one of the new tools ofmodernhydro-metallurgy. With the growing demand for metals of ever higher purity, the increasing use of unusual metals, and the necessity for treating ores of lower grade and greater complexity, solvent extraction has joined the ranks of other accepted recoverymethodsand ...Get Price

Tungsten is one of the most important refractory metals. It is used in the production of numerous end-use items such as incandescent lamps and hard materials. From its ore concentrates and oxidized scrap, tungsten is processed via ahydrometallurgicalroute. In the last 100 years there has been a significant change in itsprocessing. This paper reviews themethodsemployed in the ...Get Price

Modern coppersmelters use processedcopperore fed into a flash furnace, typically fired by oxygen which produces blistercopper, being further processed in a converter furnace. Moltencopperis poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity.Coppercan be recycled indefinitely without the base metal being compromised ...Get Price
An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
Spiral separators, which are also called spiral concentrators, are gravity devices that separate minerals of different specific gravity according to their relative movement in response to gravity, centrifugal force and other forces in the fluid medium.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
