Nickel Ore Processing Plant - China

There are two kinds of Nickel-copper sulfide ore: Copper-

nickel sulfide ore and Nickel oxide ore.

Beneficiation and

processing methods between the two are completely different.

For the Copper-nickel sulfide ores, the main beneficiation

method is flotation.

The magnetic separation and re-election

is usually secondary dressing method.

Flotation of sulfide

copper-nickel ore, it is often uses copper sulfide flotation

collector objects and foaming agents.

A basic principle of

flotation process to determine is rather that of copper into

the nickel concentrates to avoid that of nickel into the

copper concentrate.

Because nickel in copper concentrate may

be large losses in the smelting process, and copper in

nickel concentrate can be more complete recovery.

There are

the following four basic processes of Copper-nickel ore

flotation.

1 - Directly use selective flotation or partly use selective

flotation.

When copper in the ore is much higher than the

nickel content, can use this process, that select into a

separate copper concentrate.

The process has the advantage

that direct access to the lower copper concentrate

containing nickel

2 - Bulk flotation process: to process the ore that contain

lower copper than nickel, and mixed copper-nickel

concentrate will be smelted into a high grade nickel matte.

3 - Mixed-selective flotation process: From the bulk

flotation of copper ore nickel, and then carve selected from

mixed concentrates containing low nickel copper concentrate

and copper in the nickel concentrate.

The nickel concentrate

by the smelter into high-nickel matte, then nickel matte to

conduct high-flotation separation.

4 - Mixed-selective flotation and to recycle part of the

nickel for the tailings: When the various nickel ore

floatability of minerals are very different, the copper-

nickel bulk flotation, and then further recovered from the

tailings poor floatability of nickel minerals.

Copper is harmful impurities of nickel smelting, and in the

copper-nickel ore coppergrade has industrial recycling

values.

Therefore, separation of copper-nickel is an

important issue in copper-nickel ore dressing technology .

Copper-nickel separation can be divided into separation of

mixed copper-nickel concentrate and nickel matte separation

process.

The former is for ore that coarser copper and

nickel mineral and less close relationship to each other

disseminated, the latter is used for copper and nickel

mineral particle size that is very small and compact with

each other disseminated ore
