Fan Shiyong Cui Liangzhong Ma Wen Li Xiaozhong (Anhui Geology Construction Engineering Co., Ltd.) I. Introduction Early domestic tailings dams and power plants use more initial ash silo clay dam, poor water permeability; post-dam (a dam) upstream of the multi-use method to build, use mine tailing

Zinc Yang Company has many advantages after using the potential-controlled flotation high-base lead-lead process. The lead-zinc recovery rate and grade are greatly improved, and the flotation power consumption is also greatly reduced. However, under high alkali conditions, some independent silver mi

I. Theoretical basis of leaching (I) Overview Leaching is a process in which a solvent selectively dissolves a component of a mineral raw material, the purpose of which is to separate the useful component from the impurity component or the gangue component. The reagent used for leaching is called

I. Summary of economic operation of tungsten industry from 2008 to 2009 In 2007, China's tungsten industry was affected by macroeconomic regulation and control, and the volume of tungsten products import and export and the overall economic benefits of the tungsten industry all declined. The sa

First, Southwest factory using FeCl 3 bismuth leaching in mine. The raw materials used are shown in Table 1, and the process flow used is shown in Fig. 1. Table 1 铋中矿成分(%) Fig.1 Flow chart of the process of picking up the wetness method (1) Process technical condition

Lead zinc ore beneficiation general to go through the integration of rich ore to the smelting of lead, zinc metal products. The ore technology processing and smelting test is an important part of geological exploration work and one of the important basis for evaluating whether the deposit can be us

Electroplating wastewater component is very complex, in addition to cyanide (CN -), and an outer waste acid waste, heavy metals electroplating industry wastewater is potentially hazardous waste category great. The heavy metal elements of heavy metals contained in waste water are classified generall

The ore body is complex in shape, with branching and compounding, more interlayers, and the production is controlled by structure. Mining sub Venus Ridge, Shiling Shiling and South ore body. Jin Xingling ore body length 400m, angle 40 ~ 68 °, a thickness of the ore body 20 ~ 50m, 100m thickest;

Antimony ore dressing material which can be used to provide an antimony smelting; As more types of minerals, antimony ore beneficiation various methods, such as hand-selected, reselection (including heavy medium beneficiation), flotation and flotation so isolated has been applied . First, the pick

There are two types of intra-mineral air pressure measuring instruments, one for determining absolute pressure and the other for measuring relative pressure. First, the determination of absolute pressure Absolute pressure is the atmospheric pressure at the point of measurement, which is zero pres

Minor repairs: Inspect and repair the wear and lubrication of the suspension, dust, eccentric bushings, bevel gears, thrust discs, drive shaft bushings on the upper part of the broken cone. Check and repair the lubrication system and replace the oil. Inspect and repair the wear and fastening of the

Some metal ore Dan Zhonggui was fine shape disseminated in arsenopyrite and iron pyrite. Currently, in the development of a process for recovering gold and silver from such ores, it is necessary to pre-decompose sulfides by calcination, autoclave oxidation or bacterial leaching. In order to reduce
