Introduction of  2013 hot sale professional equipment gold production line                 

 

One kind of gold beneficiation process takes two closed half a broken, two second closed-circuit grinding, and then optimization of flotation, featured. And its tailings is the election of a rough one other operation, and featured concentrate tailings and swept the election are mixed together to regrinding re-election with original ore. So this process has high broken effective. 

 

The fine-grained level in final broken product is over 81.55%. Its breaking capacity is great that is 53.84 ton per hour. It has short working time, effective sorting and technical indicators for the high that can improve ore-dressing recovery and concentrate grade at the same time. Recovery ratio is improved by 3.03%, and concentrate grade is improved by 16.57 g/t, and power is reduced 21.5%, and the cost is reduced by 18.9%. And the annual economic efficiency is added by 8.6012 million Yuan.

  Flotation process for gold processing plant                                                                       

1) Crushing and grinding stage

The raw ore need to be primarily crushed by jaw crusher, and then further crushed by fine crusher. After getting the reasonable fineness, it is delivered into the ball mill by belt conveyor and feeder, then be grinded by ball mill.

 

2) Classifying stage

The spiral classifier and ball mill usually work in a close circle. The grinded ore will be delivered into spiral classifier. When the spiral classifier is working, the relatively bigger sizes will be sent back to ball mill for regrinding; while the relatively finer sizes will be overflowed to the next stage for separation.

 

3) Mixing and flotation stage

The classified ore gets into mixing tank for fully mixing. At this stage, chemical agent for foam can be added. After fully mixing, the slurry will enter into flotation machine.

When the floatation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive, meanwhile, the foams are thinning, the mineral is bounded with foams, and floats up to the surface of mineral slurry and the mineralized foam is formed. The liquid surface can be adjusted with the height of adjustment flashboard, so that the useful foams are scraped with squeegee.

 

4) Concentrator thickening and drying

After the flotation process, we could use the shaking table to elaborately select the concentrates. Then use the gold smelting furnace to smelt the gold concentrates into gold bullion.

Of course, you could also directly use the thickener to dewater the wet gold concentrates, and then use dryer to dry it.

 

 Gravity separation process for gold processing plant                                                     

1) Crushing and grinding stage

 

2) Classifying stage

 The former 2 stages of the gravity separation process are the same as that of flotation process.

 

3) Gravity separation stage

In this stage, firstly use gold centrifugal concentrator or spiral separator to recover most of the useful minerals in the gold ore. Secondly, use the shaking tables for primary concentration. Thirdly, also use shaking tables for cleaning.

 

4) Smelting stage

After getting the concentrates, use gold smelting furnace to smelt it and get the gold bullion.
