How to Process the Coltan ore mining plant effectively?
Coltan ore raw material has alluvial type and hard rock type , different type ore will use different processing method.
JXSC mine machinery Company in China has more than 30 years professional experience at coltan ore mining plant, design complete set process flowchart , provide full set coltan ore processing machines, and send engineer to mine site for equipment installation and commissioning guidance. Have already built many projects cases in Africa countries. Include: Uganda, Nigeria, Congo, Zimbabwe, Brazil,ect.
The processing capacity can be provided as per requested.
Below are the flowchart description that JXSC Engineer recommend for the coltan ore separation plant
Alluvial Coltan ore mining plant process flowchart
Feeding->washing->sieving->primary separation -> final concentration-> upgrading
Feeding: there has various kinds feeding way, depends on plant and material conditions . have choices of vibration feeder, hopper, belt feeder, or wheel loader and excavator feed directly to coltan washing machine. If there has big stone, can make grizzly bar on feeding machine or hopper to remove big waste stones.
Washing: firstly need to wash clean the clay and mud in raw material, most popular used are trommel scrubber coltan washing machine, coltan washing trommel screen or log washer.
Coltan washing trommel scrubber is for washing material that with much sticky clay, trommel screen is for wash raw material that without much sticky clay. Different ore condition , will use different washing machine.
Sieving: after washing, need to sieve out some bigger waste material,the underscreen slurry will go to next separation machine. This sieving machine can be trommel screen or vibration screen or high frequency vibration screen.
Primary separation: this process is for rough coltan separation, most often use coltan jig separator. The concentrate ore from them will go to final concentration machine.
Final Concentration: the concentrate ore from jig machine will go to coltan ore concentration machine shaking table for final concentration, can get high grade coltan concentrate ore.
Refining: if need very very high grade coltan, need to use the refining machine to upgrade it, usually can use high intensity dry magnetic separator to upgrade it, by removing other magnetic minerals and non-magnetic minerals, so can get much higher grade coltan.
Rock type coltan ore processing, the flowchart can be as below:
Feeding-> crushing->grinding->primary separation -> final concentration-> upgrading
The feeding, primary separation, final concentration and upgrading process are almost the same as above alluvial coltan process.
Below are the crushing and grinding stage description:
Crushing: this process is for crushing the big stone to smaller size before grinding.
crushers has choice of rough jaw crusher, fine jaw crusher, cone crusher, hammer crusher, roller crusher, depends on the rock feeding size and process capacity to use which kind crusher.
Grinding: after crush the coltan stone to smaller size, need to grind to power by ball mill or wet pan mill or other grinding machine, so the coltan can released out from stone. Then go to next coltan separation machine and concentration machine.
