Tin ore beneficiation production line, cassiterite beneficiation process

 
The tin ore beneficiation production line is a system for beneficiation and purification of tin ore. The tin ore beneficiation production line includes multiple processes : ore washing, sieving, gravity separation, grinding, and flotation. The specific tin ore beneficiation process should be determined according to the nature of tin ore.
 
Tin ore is divided into cassiterite , Stannite , antimony tin-lead ore, thiotin-lead ore, cylindrical tin ore, etc. Different types of tin ore beneficiation process is different, so the beneficiation production line also has different types,The following is an introduction to the beneficiation of cassiterite for reference!
 
Cassiterite is the mineral with the highest tin content among tin minerals and the main source of raw material for metallic tin. Since cassiterite mostly exists in a crystalline state, the monomer dissociation degree is high, and the specific gravity is much larger than other waste rocks, so cassiterite is mainly processed by gravity beneficiation.
 
The beneficiation process of placer cassiterite is very simply,  good quality concentrate can be obtained just by manual selection.However, the efficiency  is low, it is difficult to mine on a large scale, and the labor cost is also very large.Therefore, cassiterite ore beneficiation production line is needed to realize large-scale and high-index beneficiation work.
 
The following is a picture of a cassiterite hand-selected scene:

The tin ore in the above picture is placer tin ore, in which the tin mineral is cassiterite, which contains lots of viscous clay, the upper left picture and the upper right picture are the coarse-grained cassiterite beneficiated by manual selection. Since manual work can only select coarse-grained cassiterite, the loss rate of fine-grained cassiterite is very high, and it is necessary to use an automated mechanized tin ore dressing production line to complete the recovery and purification of coarse, medium and fine-grained tin ore ,To this end, we have designed the most simple and efficient tin ore dressing process and equipment configuration , as shown below:

Step 1: Wash the ore
The original sand tin ore enters the cylinder washing machine through the loader for washing.
(The content of cohesive soil in the ore is high, these cohesive soils enclose tin minerals and waste rock, making it impossible to separate and hindering the normal progress of  gravity beneficiation process, so the ore must be washed.)
 
step2: screen the ore
The cylindrical ore washing machine is very effective for washing such clay-bearing ores. At the same time, the ore washing product can be sieved into two particle levels, particles larger than 8mm and particles smaller than 8mm.
 
step3: crush the ore
Particles larger than 8mm enter the fine crusher for crushing, so that the final particles are smaller than 8mm.
Materials smaller than 8mm are transported to the silo by screw conveyor and mixed with the finely crushed materials.
An automatic feeding device is set under the silo to evenly feed the materials into jig machine.
 
step4:gravity separation
As the core equipment of the re-selection process, the jig machine is used to separate cassiterite and waste rock, obtain high-purity cassiterite, and discard the waste rock .
 
step5:dewater the ore
The concentrate and tailings of the jig are discharged with a large amount of water, so the tailings need to be dehydrated, and the concentrate directly enters the concentrate pool and can be excavated after natural precipitation.
We can also dehydrate the concentrate and tailings separately according to the customer's specific requirements.
