The copper or copper oxide-containing waste, leaching by ammonium carbonate solution under blast conditions, copper ammonium carbonate complex to form copper into solution, after addition of impurities leaching solution purification, to obtain a pressurized hydrogen reduction of copper; or purifica

Table rock gold mine industrial index reference project index Boundary grade (mass number of molecules) (1 × 10 - 6 ) ~ (2 × 10 - 6 ), heap leaching oxidized ore is (0.5 × 10 - 6 ) ~ (1 × 10 - 6 ) Minimum industrial grade (mass number of molecules) (2.5×10 - 6 )～(4.5�

    First, the division of mining area The division of mining area mainly depends on industrial reserve distribution, deposit occurrence conditions, water chemical type and water quality distribution characteristics, and is related to mining scale, water quality requirements, engineering

(3) Adhesive sorting In the adhesion sorting, the air is mixed with the liquid in a dispersed state, and the gas is dissolved under the pressure generated by the liquid self-weight (this pressure can reach 600 kPa), and in the subsequent depressurization process. It is also precipitated to form bub

The deposit is a tilt elongated, plate-like, multi-metal symbiotic copper ore. The ore body is 3.5km long, 50~200m wide, with an average thickness of 5~6m and a buried depth of 50~150m. The ore body contains an average of 2 to 2.5% copper, 1 to 1.5% zinc , 22% iron and a trace amount of cobalt and

1 Foreword  Magnesium is the lightest engineering metals, but the mechanical properties and corrosion resistance of pure magnesium can be low, its application is less, the mechanical properties can be improved by adding a certain amount of magnesium alloying elements and corrosion. As the

(1) Wetting phenomenon When the liquid and the solid come into contact, there are two phenomena of wetting and non-wetting. If water can wet the glass, mercury will be spherical on the glass and will not wet the glass. If the water droplets are on the surface of the paraffin, the water is in the s

I. Main schemes for the selection of copper oxide ore Copper oxide ore sorting domestic and main program are summarized as follows: (1) Flotation method: direct flotation, vulcanization flotation, etc. (2) Water-smelting method: ammonia leaching method and acid leaching method. (3) Leaching-pre

Manganese oxide, manganese ore was mainly hard manganese ore, manganese ore and water, manganese ore, gangue minerals mainly silicates, but also carbonate minerals, frequently with iron, phosphorus, and nickel, cobalt and other ingredients. The ore dressing method of manganese oxide ore is mainly b

Noble metal extraction in the refining process, the solvent extraction method has a large energy production, separation and impurity ions, high precious metal recovery, product purity and ease of operation, low cost and ease of automation and other obvious advantages, which solvent extraction metho

Reserve levels are grades that reflect the accuracy or reliability of the proven reserves. Reserve levels are one of the important indicators for measuring the degree of exploration in a deposit. According to the current regulations of China, based on the exploration research of the whole mine area

Study lead zinc ore beneficiation process a high-carbon, high-sulfur complex refractory Guo Liangming Wang Gengchen Li Yuelin He Haitao Abstract: A study on a high-carbon, high-sulfur lead-zinc ore in Inner Mongolia shows that the ore is a complex refractory lead-zinc ore. The minerals are inter-
