1. Description of nelson gold concentrator

 

The nelson gold concentrator is a new type of gravity concentration equipment for concentrating gold and other high density minerals. The centrifugal machine gets many competitive advantages compared with other concentration machines which create high returns for the investors.

 

2. Application of nelson gold concentrator

 

 

STLB nelson gold concentrator is kind centrifugal concentration equipment. It can be used not only for placer gold mining, but also for hard rock mining to recover the natural gold, replacing amalgamation. It is also used to recover gold from the old tailings.

 

Since 1985, three models of nelson gold concentrator have been developed. Application shows that the recovery can be as high as 99%, especially for the case in recovering the natural gold in lode ore with 65% of the ore having a milling size of-0.074mm, the recovery for the natural gold is expected up to 98%. For that natural gold of 0.004mm in particle size, the recovery is 97%. The cleaning up cycle is 1~4 hours. And the upgrade ratio is up to 1,000 times.

 

3. Features of nelson gold concentrator

 

 

High recovery rate: Through our test, the recovery rate for placer gold can be 98% or more, for rock gold, the recovery rate could reach 97% when the feeding size is below 0.04mm.

 

High efficiency: STL60 nelson gold concentrator has a capacity of 10-20TPH, and STL100 nelson gold concentrator has a capacity of 50-80TPH. Only one machine could give you such a high capacity and high recovery rate. It's the most efficient concentration equipment in our factory.

 

Easy to install: only a small leveled place required. It's a complete machine, before starting it, only need to connect the fluidization water and power.

 

Easy to adjust: there are only 2 factors that will affect the recovery result, they are water pressure and feeding size. By giving proper water pressure and feeding size, you could get the best recovery effect.

 

Easy to operate:  after finishing the water pressure and feeding size adjust, what U have to do is to fetch the concentrates every 2-4 hours. (Depending on the grade of the mine)

 

No pollution: this machine only consumes water and electric power, and exhaust tailings and water. Low noise, no chemical agent involved.

 

Reliable:  this nelson gold concentrator gets a simple & tough structure, the main body is made by strong steel, and the concentrate cone is made by stainless steel. And the bearing is greased to keep it running well.
