Gravity Separator for Copper Ore---Case of Copper Sulfide From The Philippines

 

Floatation separation is used to beneficiate copper oxide and copper sulfide, while jigging gravity separation is rarely involved. So for most of copper ore, jigging separation does not work. But for some copper ore, it does work well to do the pre-separation and then floatation separation can be adopted for further beneficiation and this will save a lot of operating cost.

The following picture is ore of copper sulfide from the Philippines. Here we will introduce the jigger pre-separation for copper ore.
 

 
From the picture, this copper ore has clear bound between copper mineral and gangue with big embedded size and the copper mineral is not even in the gangue. All natures show that jigging separation can do a great job in ore-pre-separation to remove most of the waste stones. And the concentrate from jigger can go for the floatation separation to lower the floatation plant cost and the pollution to environment.


The Philippines has a high requirement about the environment, and the client asked for easy and practical gravity separation to remove waste stone and then small-scale floatation separation can be used to purify lowering the floatation plant cost and floatation separation operation cost. The treatment capacity has been highly improved because of the large quantity of waste stone removed by the jigger.

Copper Ore Beneficiation Plant In The Philippines

Results of the small jigging separation test met needs of client. In the test most of waste stone is removed, and copper sulfide is enriched, and the whole processing was showed perfectly no matter the coarse concentrate or the recovery rate. The client expressed on site jigging gravity separation as core pre-separation for copper ore.


Copper ore has different types and matures, and most of copper ore cannot be beneficiated by gravity separation, but this jigging gravity cannot work for all copper ores.  Ore beneficiation flow sheet is designed according to the ore natures. For this kind of copper ore, if floatation separation is used directly, the copper ore needs milling and the milling cost will be high with higher floatation separation plant cost and smaller handling capacity. So for this kind of copper ore, the jigger is the ideal choice, a great help for the latter floatation separation.


The embedded situation and size of embedded size decides whether the copper ore can be beneficiated by jigging gravity separation. Usually, copper ore of large size embedded or liberation after just crushing or milling can be pre-separated by jigging separators. The density of copper mineral is high while the intergrowth gangue is low, so gravity separation can help to gain great separation efficiency.
 
The gravity separation machine for copper ore is usually jigger with its high recovery rate, large treatment capacity, low beneficiation cost, and great beneficiation efficiency. In the pre-separation of copper ore, jigger is required to gain highest recovery rate as kind of pre-separation machine. Tailing- loss is avoided by jigger to a large extent, so jigging pre-separation can help to gain great beneficiation efficiency for coarse copper grain size embedded.
