Xinhai separates two useful minerals that with similar floatability into the mixed concentrate, and then floats each concentrate. That is, copper sulphide and lead ore with similar floatability are selected as mixed concentrate, and copper and lead is separated. Then the tailings were reactivated to separate the zinc concentrate.

With the principle of " easiness to hardness ", Xinhai divides the recovered minerals into two parts: easy-to-float and difficult-to-float according to the difference of natural floatability, and then separate the copper, lead and zinc concentrate from the mixed concentrate.

In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, its a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents. Xinhai strictly implements the reagent system, controls the dosage of reagent, reduces multiple circulation and loss, then strengthens the flotation effect.

Since desorption and electrolysis does not require different temperatures, it is not necessary to change temperature. The quickness and efficiency of machine dramatically diminishes gross electricity consumption by 1/2-1/4.

In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, AuCN2 is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.

cu-pb-zn, copper-lead-zinc ores, copper lead zinc flotation

It is reported that more than 90% of non-ferrous metal ores (copper, lead, zinc, etc.) adopt flotation process, especially for those with fine grain and complex symbiosis. Flotation process can achieve ideal separation effect, and separately recover low-grade ore then enrich multiple high-grade concentrates. Different ore properties means different flotation process. According to the dissemination characteristics of metal minerals, Xinhai has determined four kinds of flotation processes:

Xinhai separates two useful minerals that with similar floatability into the mixed concentrate, and then floats each concentrate. That is, copper sulphide and lead ore with similar floatability are selected as mixed concentrate, and copper and lead is separated. Then the tailings were reactivated to separate the zinc concentrate.

With the principle of " easiness to hardness ", Xinhai divides the recovered minerals into two parts: easy-to-float and difficult-to-float according to the difference of natural floatability, and then separate the copper, lead and zinc concentrate from the mixed concentrate.

how does the desorption electrolysis system work? - xinhai

Desorption Electrolysis System is a kind of gold ore dressing combination equipment to obtain gold mud from carbon by desorption and electrowinning, and it is widely applied to recovering solid gold from carbons in the cyaniding process.

Desorption Electrolysis System used of gold mine processing consists of many devices, which consists of analytical column, electrolytic tank, filter, heater, analytical solution agitation tank, control electric wheel, DC power supply, measuring instrument, etc.

2. Since desorption and electrolysis does not require different temperatures, it is not necessary to change temperature. The quickness and efficiency of machine dramatically diminishes gross electricity consumption by 1/2-1/4.

In gold electrowinning process, when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, AuCN2 is replaced by anion and the gold desorption is achieved. After the carbons loaded with gold are desorbed, pregnant solution is process via ionization. At last, solid gold is attained.

It can be difficult to think abstractly about the working principle of Desorption Electrolysis. Xinhai makes a 3D demo video which is of great help to make it out. Every single part and working principles of Desorption Electrolysis System are showed in Xinhai 3D video, which is really convenient for you to see the structure and working principles of those large equipment.
