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
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
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
