Note: Flotation is divided into three systems. The numbers in the table on the previous page are only the number of one system.
The concentrate is dehydrated in the second stage. The final concentrate water is 10~12% for lead and zinc and 14% for sulfur.
1985 beneficiation plant power consumption 33.5kw.h / t, where crushing and screening 3.2kw.h / t, grinding 8.8 kw.h / t, flotation 9.5 kw.h / t, concentrate dewatering 7.0 kw.h / t, water supply 5.0 kw.h/t.
According to the characteristics of the ore, the plant adopts a floatable process to improve the grade of lead concentrate and the production index is stable. From 1980 to 1985, the grade of lead concentrate has been 71~72%, the recovery rate is 89~91%, the grade of zinc concentrate is 44~44.5%, and the recovery rate is 92~93%. Concentrate dewatering gradually adopts high-efficiency jet pump instead of water ring vacuum pump. Although there is no significant difference between the two, the jet pump can reduce the power consumption by 40%, which is equivalent to 2.8kw.h/t per ton of concentrate. It is one of the factories with low power consumption in China's lead-zinc ore dressing plant.
The process indicators, unit consumption indicators and main equipment of the concentrator are shown in the following table:
