選金方法基本上分為兩大類,一類是化學(xué)方法，他是根據(jù)金能與其他物質(zhì)相結(jié)合或化合的特性而發(fā)展起來的方法，包括混汞法，浮選法和氰化法。化學(xué)方法選金有一定的優(yōu)點(diǎn)，但環(huán)境污染也相當(dāng)嚴(yán)重。第二類是物理方法，利用重力原理將進(jìn)金顆粒與比重較輕的其他物質(zhì)分離，如采用跳汰、搖床、溜槽、圓錐選金機(jī)等設(shè)備進(jìn)行選金。振動(dòng)離心選金機(jī)是屬于重力選金的新型設(shè)備，從俄羅斯引進(jìn)的世界先進(jìn)選金技術(shù)。
Basically, gold concentration technique is classified into chemical method and physical method. The former that is further divided into amalgamation, floatation and cyanidation was developed based on the property of gold by which the gold can combines with other substances. Chemical process shows certain advantages while resulting in rather serious environment pollution. With respect to physical process, the Law of Gravity is adopted to separate gold grains from other lighter substances. This technique is used for gold concentration with jigging machine, table concentrator, glide chute and conical concentrator. Vibrating centrifugal concentrator is a new type of machine using the Law of Gravity, a globally advanced concentration technique introduced from Russia.
在選金過程中，振動(dòng)離心選金機(jī)中的選金斗高速旋轉(zhuǎn)，漿液進(jìn)入選金斗，漿液中的顆粒受到旋轉(zhuǎn)產(chǎn)生的徑向向外的離心力作用，又不時(shí)的受到徑向向內(nèi)的振動(dòng)力作用，不同比重的顆粒在兩種力的作用下分離開，金顆粒被集中在選金斗內(nèi)，而其他比重輕的顆粒被水夾帶排除選金斗外。
During the concentration of gold, the concentration bin rotates at a high speed. As a result, when the pulp gets into the bin, the particles therein will be under the effect of radial outward centrifugal force due to the rotation and the effect of radial inward vibration from time to time. The particles with different specific gravities are separated under the joint action of the two forces. As a result, gold grains will concentrate in gold bin, and the particles with smaller specific gravity will be entrained in water and thus be discharged from the gold bin.
新型無污染高效振動(dòng)離心選金機(jī)適用于選取單體金和比重大的大顆粒包裹金，對(duì)難處理金礦中15微米以上的微細(xì)單體金的回收率高于其他進(jìn)口設(shè)備至少百分之十，巖金礦石中單體金居多，因此新型無污染高效振動(dòng)離心選金機(jī)適用于大多數(shù)巖金礦和沙金礦的選金。特別是難處理金礦的****設(shè)備。對(duì)浮選和氰化后的尾礦的回收也有很高的經(jīng)濟(jì)價(jià)值。
The new type of pollution-free high-efficiency vibrating centrifugal concentrator is applicable for selection of monomer gold and the gold in large particles with relatively high specific gravity, presenting a recovery rate of fine monomer gold with a particle size ≥15um from refractory gold ore at least 10% higher than other imported equipment. Since most gold ore contains monomer gold, the new type of pollution-free high efficiency vibrating centrifugal concentrator applies to the gold concentration from most rock and sand gold mines, particularly from refractory gold ore. This machine also presents extremely high economic value for tailings recovery after floatation and cyanidation.
為了提高選金的回收率，在選金的生產(chǎn)流程中使用四臺(tái)或五臺(tái)離心機(jī)選金，組成一條日處理25噸的生產(chǎn)流水線。在規(guī)模化生產(chǎn)中，可以設(shè)計(jì)安裝幾條生產(chǎn)線，以滿足日處理50噸、100噸和200噸以上的選金生產(chǎn)的需要。
In order to improve the recovery rate, four or five centrifugal concentrators are used in concentration process to establish a production line with a capacity of 25 tons/day. In large-scale production, several production lines can be designed and installed to meet the requirements of gold concentration capacity of 50, 100 and 200 tons.
