Gold mine equipment process

The content of gold in the ore is very low. In order to extract gold, it is necessary to break and grind the ore and use the beneficiation method to pre-enrich or separate the gold from the ore. Gold ore dressing is more use of re-election and flotation, re-election method in the production of gold in the possession of a very important position, flotation method is widely used in the rock and gold mining method, the current 80% of China's rock gold mine The use of this method of gold, mineral processing technology and equipment level has been greatly improved.

Crushing and grinding

According to the survey, the use of jaw crusher jaw crusher for coarse crushing, the use of standard cone crusher in the broken, and crushing is the use of short-headed conical crater and the roller crushing machine. In the small and medium-sized gold bullion factory mostly used two closed mine mine, large-scale selection of gold plant with three sections of a closed mine process.

In order to improve the mineral processing capacity, tap the potential of the equipment, the mine process has been modified to improve the utilization factor of the mill, the main measures taken is to implement more broken and less grinding, reducing the ore grain size.

Gold ore crusher process:

Gold ore crusher

Large pieces of gold by the silo by the vibrating feeder evenly sent to a broken (jaw crusher) for coarse crushing, shredded gold from the belt conveyor to the two broken (impact crusher or cone Crusher) for further crushing; crushed gold from the belt conveyor into the vibrating screen for screening, screening out several different sizes, different specifications of gold, to meet the grain size requirements of the gold by the finished belt conveyor Sent to the finished material pile; do not meet the grain size requirements of the gold mine by the belt conveyor back to the counter-crusher or cone crusher to break again to form a closed loop many times. Finished particle size can be combined and graded according to the needs of users, in order to protect the environment, can be equipped with auxiliary gold mining dust removal equipment.


Re-election in the rock gold mine is widely used, as an auxiliary process, in the grinding circuit recovery of coarse gold, flotation and cyanidation process to create favorable conditions to improve the ore processing indicators to improve the total recovery of gold, And reduce costs to play a positive role. Shandong Province, about more than 10 selection of gold plant using the re-election of this process, the average total recovery rate can be increased by 2% to 3%, the enterprise economic benefits, according to incomplete statistics, each year can get millions of dollars in profits. Henan, Hunan, Inner Mongolia and other provinces (regions) also achieved good results, using the main equipment chute, shaker, jig and short cone cyclone. From the majority of China's gold mine, floating-heavy joint process (flotation tailings re-election) is suitable for use in the future should be vigorously promote the stage grinding stage selection process, to promote the early harvest of the principle of beneficiation.


According to the survey, about 80% of China's rock and gold mines using flotation method of the election, the output of the concentrate sent to the processing of colored smelters. Due to the growing development of cyanide gold and enterprises to improve economic efficiency and reduce the loss of transportation, in recent years, the product structure has undergone great changes, take more local treatment (of course, due to the contradiction between the election and pricing And other issues, forcing the mine on the spot to deal with) to promote the flotation process has a greater development in the gold production occupies a considerable important position. Usually there are two pre-flotation and mixed flotation processes. In recent years in the process of transformation and pharmaceutical additives system has made new progress, flotation recovery rate is also significantly improved. According to the national more than 40 gold-plated plants, flotation process indicators survey results show that sulfide flotation recovery rate of 90%, a few as high as 95% to 97%; ore recovery rate of 75%; individual to 80% 85%. In recent years, the flotation process innovation and scientific research results are many, the effect is obvious. Stage grinding process, heavy-floating joint process, is the main trend of the development of flotation process in China. Such as Xiangxi gold mine using heavy-floating joint process, the stage of grinding stage selection, access to better indicators, the recovery rate increased by 6%; Jiaojia gold mine, Wulong gold mine, Wenyu gold mine, To achieve a certain effect. Another example is the Metro gold mine, the original process for the direct ore flotation, due to higher mud (ore itself with high mud, plus mining tailings cementation filling strength is not enough to bring part of the sediment) to continuous decline in mineral processing indicators. The recovery rate increased from 93.05% to 95.01%, and the concentrate grade was 135g / t to 140g / t, which stabilized the production. Jinchangyu gold mine due to the decline in ore grade year by year, so the flotation index decreased, with the Shenyang Gold Institute and other units to study the use of branch flotation process to improve the flotation index and concentrate grade. This scientific research (in January 1988 the gold company through the technical appraisal), for the flotation process transformation has been a new inspiration. Of course, the flotation method and other methods as is not a panacea, it is impossible for all gold-bearing ore are effective, mainly to consider the nature of the ore, in the choice of process, the need for a variety of arguments and tests.

In recent years, in order to improve the sorting effect, in the process of continuous improvement at the same time, the system of pharmaceutical additives and mixed medication also made a lot of improvement and research, in the dosing to achieve automatic control has also made new progress.


Gold ore process

Gold ore flotation machine

Gold ore flotation machine main process: in the flotation process, the mineral ups and downs has nothing to do with the mineral density. Such as chalcopyrite and quartz, the former density of 4.2, the latter is 2.68, but the heavy mineral chalcopyrite is easy to float, but rather sink at the bottom of the quartz. The study found that the floatability of minerals and its affinity for the size of the water, all with water affinity, easy to wet water minerals, difficult to attach to the bubbles on the difficult to float. And the water affinity is small, not easy to water wet mineral, easy to float. Flotation and other mineral processing methods, to do a good job sorting before the material preparation work, that is, ore to go through the grinding grading, to achieve the appropriate concentration of flotation fineness.

In addition, the flotation also has the following basic operations: First, the adjustment of pulp and flotation agent to join. The purpose is to create a difference in the nature of the mineral surface, that is, to change the wetting of the mineral surface, adjust the mineral surface selectivity, so that some mineral particles can be attached to the gas saturation, and some can not be attached to the bubble. Second, stir and cause a lot of bubbles. By means of the aerator and agitator of the flotation machine, the air in the slurry is dispersed to form a large number of bubbles, or the air dissolved in the slurry is formed to be slightly precipitated. Third, the mineralization of bubbles. The ore particles are selectively adhered to the bubble, which is the basic behavior in the flotation process. Flotation is based on mineral water wetting different mineral processing methods. Generally the nature of the minerals easy to float and difficult to float as a mineral floatability. Flotation is the use of mineral floatability difference to sort the mineral. In the modern flotation process, the application of flotation agents is particularly important, because the flotation agent treatment, you can change the floatability of minerals, so that the floating minerals can be selectively attached to the bubble, so as to achieve the purpose of mineral processing.
