Some mine or factory production of gold, silver products, refined gold and silver is not finished, but not high fineness of coarse gold, silver or coarse gold and silver without isolation of crude gold. Since these products are not directly sold in the unit for purification, it is necessary to carr
Figure 46 is a schematic diagram of the operation of the QSB type cyclone jet mill produced by Shanghai Chemical Machinery No. 3 Plant in China; this type of jet mill has been serialized. [next] The structure of PQF type cyclone jet mill produced by Sichuan Mianzhu Chemical Plant is similar to
Socialist industrial enterprise financial management, is the various forms of funding, distribution and use of enterprise production and management activities needed to plan, organize, regulate, and supervise the general term for accounting work. The task of financial management is to determine the
Example galena in the lead zinc ore, as measured by using a particle diameter of the cross-sectional diameter d (A) i and (N A) i as shown in Table 2, the test meter - Calculate the (N V ) j and d (V) of the galena. - 1 d(V) = —— Σ(NV)j·(dv)j = 204.68mm/2267.21 = 0.0903
Mine ore properties belonging to a refractory gold ore, more than 90% gold package, a mine, two medium-temperature atmospheric beneficiation plant preoxidation - Cyanide gold extraction process, production capacity of 300t / d, a cyano end 2005 The tailings are about 500,000 tons, with an average g
A first seam antimony tin mine roof is unstable shales, f = 4 ~ 6, joints, faults developed after exposure easy to take off. The ore is a ash-containing ash, f=12~16, which is hard and stable. The thickness of the ore body is generally 2~3m, the local ore section is 3~5m, and the inclination angle
   Brochantite Cu 4 (OH) 6 S0 4 may be dissolved in water forms a copper sulfate solution. Other copper oxide minerals can react with acids to form copper ions and dissolve in human water, so their leaching reactions are mainly related to the pH of the solution. The pH- stability diagram
Demand for fixed capital management are: 1. Correctly verify the quantity required for fixed assets to ensure the smooth progress of production and operation activities of the enterprise. 2. Use and manage fixed assets, give full play to the effectiveness of fixed assets, and improve the utilizat
For weakly alkaline gold- loaded resins, the best method is to use a sodium hydroxide solution with a pH of 13 at normal temperature and pressure for good desorption; for strong alkaline gold-loaded resins, there are more desorbents and sodium hypochlorite. The method, the acid thiourea method, the
A gold deposit in Sichuan Province is a large-scale rock gold deposit discovered in recent years. The confirmation of the mineral industry index is the basis for providing the geological department with the circled ore body and submitting the gold exploration geology report. I. Basis for the devel
2. The technical analysis of the causes of low effectiveness Under the same conditions of wind strength, the direct result of the current large-scale wind turbine single blade super long design will lead to a reduction in the rotation speed of the wind wheel, resulting in an increase in t
Since the 1990s, China's aluminum industry has developed rapidly, its scale has expanded rapidly, and its output has continued to grow. By the end of 2002, the annual production capacity of aluminum processing mainframes had reached nearly 5 million t/a, and the comprehensive production capacit
