The crude bismuth and zinc in addition to silver-rich silver refining slag output by the de-segregation of bismuth, prior to recovering the silver, the slag must be Ag-Zn eluted off the zinc, both the recovery of zinc, and for recovery of silver Good pretreatment. Dezincification can be carried ou

F Flow conditions An important parameter for calculating the minimum discharge opening width of a arch or knot is the critical open yield strength ƒ cc . The solution to ƒ cc is to represent the flow factor ƒ 流动 on the flow function FF, the intersection CC is ƒ. e.g. Johns

      The fine sieve saddle mine in the mid-1980s developed, the full range of a total of four kinds of specifications, mainly used in metal ore processing plant to replace a grinding circuit in the low classification efficiency spiral classifier, it can also be used in other sector

Scrap iron scrap iron and steel is a generic term for areas of production and consumption generated. The scrap produced in the production field mainly refers to steel slag, scrap billet, scrap sub-materials, scraps, various scrapping equipment or equipment produced in the production fields of stee

Impurities in the crude lead, bismuth, silicon into the anode mud of electrolytic lead hydrofluoric acid. After the anode mud is reduced and smelted, the bismuth enters the precious lead together with gold and silver , is charged into a silver furnace, and is oxidized to form slag, and the rutheniu

Abstract: The mercury and antimony ore in Qinling are all produced in the Qinling trough, which is often distributed in zones and relatively concentrated. The distribution of deposits (points) is controlled by both sedimentary rock layers and fault structures. Minerals are concentrated in two ore b

I. Overview Nanshanhai Rare Earth Mine is located in the territory of Guangdong Province. It is one of the large-scale monazite-bearing coastal sand deposits in China. The mine began exploration in 1961, was built in 1970, and put into operation in 1973. The entire mine includes mining sites, roug

First, the effect of temperature on activity and activity coefficient The commonly given activity coefficient is the value at 25 ° C (298 K). For other activity coefficients, Meissner proposes the following equation to correct the q o value. (1) Where Δt = t-25; the values ​�

The quality of sinter is mainly manifested in strength and reductibility. They are related to the development degree of binder phase, crystallization conditions, number and characteristics of pores, cracks, etc., and also related to the strength and reducibility of binder phase minerals. . In recen

1, sintering sintering A powder or compact heat treatment at a temperature below the melting point of the main component, object by metallurgically bonding between the particles to increase its strength. 2 , packing packingmaterial A material in which a compact is embedded during the pre-firing

    GXL-500 double cone compound type cyclone classifier is a high-efficiency intensified centrifugal grading equipment successfully developed by the North Mine Institute in 1993. Its innovation lies in the use of a special structure that can form a secondary circulation, with enhanced cla

First, the discovery of magnesium (1) 1808 British chemist David (H.Davy) a mixture of magnesium oxide and mercury electrolytic magnesium amalgam obtained was first obtained metallic magnesium. (2) In 1828, the French scientist Abbésy (AABBussy) used potassium to reduce molten magnesium chlori
