[ specifiion for sulfur dilute ore concentrator ]

Ore with a relatively high sulfur content, containing various amounts of ferrous and nonferrous sulfides, and particularly a relatively small amount of copper sulfide, is subjected to a controlled oxidation leach in an aqueous medium at elevated temperatures and pressures, to convert the nonferrous sulfides into water soluble sulfates with only slight concomitant oxidation of the ferrous sulfides

pre-concentration of copper ores by high voltage pulses

pre-concentration of copper ores by high voltage pulses

Aug 01, 2015 A novel ore pre-concentration technique using high voltage pulses is proposed in this study. The technique utilises metalliferous grain-induced selective breakage, under a controlled pulse energy loading, and size-based screening to separate the feed ore into body breakage and surface breakage products for splitting of ores by grade

Mar 20, 2016 400 ton daily rate, 200 ml per min of 5% xanthate solution Lbs. per ton = 200 x 1 x 5/31.7 x 400 = .079. Interpretation of Comparative Metallurgical Calculations. Generally speaking, the purpose of ore concentration is to increase the value of an ore by recovering most of its valuable contents in one or more concentrated products

copper mining and extraction sulfide ores

copper mining and extraction sulfide ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. For example: FeO(s) + SiO 2 (s) FeO.SiO 2 (slag) This

copper mining and extraction: oxide ores

copper mining and extraction: oxide ores

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (1114), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Jul 12, 2021 Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process Beneficiation methods of copper sulfide ore Copper sulfide can be divided into single copper ore, copper sulfur ore, copper-molybdenum deposit, copper nickel, carrollite and so on

removing of sulphur and iron from copper ore | solution

removing of sulphur and iron from copper ore | solution

Dec 09, 2012 This lowered sulphur emissions to about 17% of sulphur in the ore. a two-stadium pressure leach to remove all the copper and the residual iron and nickel in . As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding

accelerating leaching of copper ore with surfactant and

accelerating leaching of copper ore with surfactant and

Mar 08, 2019 To solve the problem of low permeability and lower extraction rates of high-mud ores, a surfactant was added as a penetrant to the pregnant leaching solution during column leaching tests. On the basis of the theories of physical chemistry and seepage flow mechanics, the mechanism by which seepage is enhanced under the effects of the surfactant was analyzed. The results show that the

copper mining and production processes explained

Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in

enhanced methods for nickel recovery from low-grade ores

enhanced methods for nickel recovery from low-grade ores

Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals
