Sulphide ores and concentrates Most zinc ores occur as sulphides and, as such, are amenable to upgrading by flotation. The traditional treatment route includes smelting of the concentrates, followed by hydromet allurgical processing to produce electrolytic zinc metal. Direct ore processing via a hydrometallurgical route could enable
It is said that it is necessary to use crushing equipment to extract nickel from its ore. 2 The extraction process of nickel. The extraction of nickel process generally consists of crushing, sieving, washing, re selection, grinding, and slurry concentration, or the nickel leaching method.
This process characterized by easier operation, longer flotation time, fewer concentrate flotation and process concentrate ore from different stages of separation, which can recovery nickel ore as soon as possible in the flotation process. The solution of copper sulfide nickel ore get nickel grade of 12% of high profit.
Because the conversion of nickel sulfide directly to metal would require an extremely high temperature , the removal of sulfur at this stage of the converting process is controlled in order to produce the 7075 percent nickel matte, which has a lower melting point. On the other hand, the relatively high ratio of sulfur to nickel in most nickel concentrates increases the burden of sulfur containment in the smelters.
Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most well known purification processes is called the Mond Process, which is an extracting and purifying process developed by Ludwig Mond in 1899.
6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist.
The best concentration method for zinc ore is known as froth flotation. Concentration of Ore: Froth Flotation Process Froth Flotation process is mainly used to remove gangue from sulphide ores. The ore is powdered and a suspension is created in water.
The basic steps in this process include preparation of a zinc sulfate solution by leaching zinc oxide calcines in dilute sulfuric acid, purification of the resulting zinc sulfate solution, and electrolysis of the purified solution.
