Abstract
A process for separating the valuable metallic ore concentrate from placer tailings of non-ferrous metal (copper or tungsten) includes concentrating the valuable metallic ore by table and conventional floatation or gravitation separation. Its advantage is low cost.
Description
Technical field
The present invention relates to a kind of valuable metal concentrate method of from the non-ferrous metal tailings, choosing; Particularly in the copper tailings ore deposit after the flotation of copper raw ore or choose the method for valuable metal concentrate in the tungsten tailings ore deposit of tungsten raw ore after gravity treatment.
Background technology
At present, various non-ferrous metal raw ores extract valuable metal by floatation or gravity separation method, generally discard as trash discharge through the non-ferrous metal tailings after the flotation or after the gravity treatment; But also leave a spot of valuable metal in the non-ferrous metal tailings has wasted like this; Like this, the valuable metal in the non-ferrous metal tailings ore deposit is not fully extracted, and is waste, is again an economic loss.
Summary of the invention
The object of the present invention is to provide a kind of low cost, from non-ferrous metal tailings ore deposit, reclaim the method for choosing the valuable metal concentrate.The valuable metal that is discarded in the tailings is turned waste into wealth, create economic benefit, particular content of the present invention is to adopt tailings ore deposit behind the non-ferro metals floatation or the tailings ore deposit after the gravity treatment as base-material, become the valuable metal mineral aggregate through the screening enrichment, and reach conventional floatation or the requirement of gravity separation method tenor, again the valuable metal mineral aggregate is made it to reach commodity concentrate standard through conventional floatation or gravity separation method, concrete steps are as follows:
A, the tailings mineral aggregate that will contain the valency metal are transported to shaking table, separately emit mud and most of sandstone in the tailings by the shaking table double vibrations, realize the first enrichment of valuable metal, again shaking table is delivered in first enrichment ore deposit and carried out the secondary enrichment, the valuable metal mineral aggregate is reached can be with the conventional floatation or the content requirement of gravity separation method further;
B, valuable metal mineral aggregate that will enrichment from the tailings ore deposit make it to reach the standard of commodity concentrate again with conventional floatation or gravity separation method.
In sum, a small amount of valuable metal recovery that The present invention be directed in the tailings ore deposit is selected to concentrate, reaches the purpose of creating economic benefit, operating cost of the present invention is low, fully reclaim the value of the valuable metal in the non-ferrous metal tailings, turn waste into wealth, create economic benefit.
The specific embodiment
1, the present invention is as base-material with the tailings ore deposit after non-ferro metals floatation or the gravity treatment, with shaking table the valuable metal mineral aggregate in the tailings is carried out first enrichment, secondary enrichment then, the valuable metal mineral aggregate is reached can be with the conventional floatation or the further content requirement of gravity separation method.
For example: get and contain Au=0.00005%, Ag=0.0053%, the copper tailings of Cu=0.96%, contain Cu 〉=4% in the valuable metal mineral aggregate after the enrichment of secondary shaking table, Ag 〉=0.0173%, Au＞0.00012% this shows, the valuable metal mineral aggregate that obtains after the shaking table operation can reach with conventional floatation content requirement.Simultaneously, for the tungsten tailings, then concentration ratio is high more good more, and promptly the metal mineral aggregate tungstenic amount of tungsten tailings after this two steps process operations is high more good more.
2, valuable metal mineral aggregate that will enrichment from the tailings ore deposit makes it mineral aggregate with conventional floatation or gravity separation method and reaches the requirement of commodity non-ferrous metal concentrate, for example the copper tailings is through above-mentioned two step operation and conventional flotation, make content 〉=22% of Cu, the tungsten tailings makes W content reach commodity tungsten concentrate I level second standard by conventional reselection of tungsten ore method after above-mentioned two step operations again.
Claims (1)
1, a kind of method of from the non-ferrous metal tailings expands, choosing the valuable metal concentrate, it is characterized in that adopting tailings ore deposit behind the non-ferro metals floatation or the tailings ore deposit after the gravity treatment as base-material, become the valuable metal mineral aggregate through the screening enrichment, again the valuable metal mineral aggregate is made it to reach commodity concentrate standard through conventional floatation or gravity separation method, concrete steps are as follows:
A, the tailings mineral aggregate that will contain the valency metal are transported to shaking table, separately emit mud and most of sandstone in the tailings by the shaking table double vibrations, realize the first enrichment of valuable metal, again shaking table is delivered in first enrichment ore deposit and carried out the secondary enrichment, the valuable metal mineral aggregate is reached can be with the conventional floatation or the content requirement of gravity separation method further;
B, valuable metal mineral aggregate that will enrichment from the tailings ore deposit make it to reach the standard of commodity concentrate again with conventional floatation or gravity separation method.
