Description
Technical field
The present invention relates to a kind of metallurgical technology of handling nickeliferous high cobalt sulfuration material.
Background technology
The main chemical constitution of nickeliferous high cobalt material is (specifically seeing table 1) such as Ni, Co, Cu, S; And have Co, the higher characteristics of S of containing, adopt methods such as ordinary method such as normal pressure acidleach, sulfurization roasting-acidleach to handle all to exist that the metal direct yield is low, tooling cost is high and the problem of operating environment difference.
The nickeliferous high cobalt sulfuration material composition (%) of table 1.

Summary of the invention
The objective of the invention is to adopt ordinary method to handle the deficiency that exists, a kind of new leaching metallurgical technology of handling nickeliferous high cobalt sulfuration material is provided, make that Ni, the Co more than 98% got into solution by leaching in the nickeliferous high cobalt sulfuration material to nickeliferous high cobalt sulfide.
The objective of the invention is to realize through following technical scheme: a kind of nickeliferous high cobalt sulfide extract technology, leach through normal pressure preheating, pressurization, the leach liquor that obtains the enriched in metals cobalt can directly get into the cobalt production system, and each section of technical process is specific as follows:
A) said nickeliferous high cobalt sulfide is carried out pulp in the dilution heat of sulfuric acid of 10-20 g/l; Control dilute sulphuric acid volume is 6:1 with the ratio of said nickeliferous high cobalt sulfide quality; The pulp temperature is 40-50 ℃, and the pulp time is 2～3h, and pulp terminal point sulfuric acid concentration is 5-15 g/l;
B) control normal pressure preheating temperature is 80～85 ℃;
C) the control pressurization is leached: control dilute sulphuric acid volume is 6:1 with the ratio of said nickeliferous high cobalt sulfide quality, and temperature of reaction is 145～165 ℃, and the leaching oxygen partial pressure is 0.20-0.25MPa, and the reaction times is 6～8h.
Because nickeliferous high cobalt sulfide contains Cu, Fe is lower; Therefore the present invention is through adopting normal pressure preheating, pressure leaching process; Make total slag rate be about 1%; Thereby guaranteed Ni, the higher leaching yield of Co, obtained containing nickel, the cobalt sulfate liquor of cobalt greater than 50g/l, Ni, Co in the promptly nickeliferous high cobalt sulfuration material more than 98% are got into solution by leaching.This solution directly send the cobalt production system to produce the cobalt product.
In addition, the present invention is simple efficient, an eco-friendly flow process, is fit to handle nickeliferous high cobalt sulfuration material.

Embodiment
Below in conjunction with accompanying drawing the present invention and effect thereof are further described.
A kind of nickeliferous high cobalt sulfide extract technology leaches through normal pressure preheating, pressurization, and the leach liquor that obtains the enriched in metals cobalt can directly get into the cobalt production system, and its each section of technical process is characterised in that:
A) nickeliferous high cobalt sulfide is carried out pulp in the dilution heat of sulfuric acid of sulfur acid 10-20 g/l; The ratio 6:1 of control dilute sulphuric acid volume and said nickeliferous high cobalt sulfide quality; The pulp temperature is 40-50 ℃, and the pulp time is 2～3h, and pulp terminal point sulfuric acid concentration is 5-15 g/l.
B) control normal pressure preheating temperature is 80～85 ℃.
C) the control pressurization is leached: control dilute sulphuric acid volume is 6:1 with the ratio of said nickeliferous high cobalt sulfide quality, and temperature of reaction is 145～165 ℃, and the leaching oxygen partial pressure is 0.20-0.25MPa, and the reaction times is 6～8h.
Concrete work flow of the present invention is: the preceding liquid (acid solution) of nickeliferous high cobalt sulfuration material and preparation carries out the pulp operation earlier; Ore pulp after the pulp is after the normal pressure leaching vat are heated preheating; Be delivered to the autoclave leaching of pressurizeing through force (forcing) pump, pressurization is leached the back ore pulp through filtering with plate and frame(type)filter press behind the flash drum cooling decompression, and filter residue returns pyrogenic attack; The filtrating part is returned the preceding liquid (acid solution) of preparation, and all the other send the cobalt production system.
The present invention produces result of implementation and sees table 2,3.
