Processing of ores |
| abstract |
This invention relates to a process for the treatment of a sulphide ore containing pentlandite, pyrrhotite and possibly talc. The ore is first ground preferably under substantially non-reducing conditions and then the ground ore is subjected to a talc pre-float wherein fast floating talc can be recovered in a preliminary stage of flotation without an excessive loss of nickel. The sulphide-containing tailing from the talc pre-float is then subject to split conditioning followed by flotation in the absence of copper sulphate so as to selectively float pentlandite from pyrrhotite. The pentlandite float product may then be subjected to a conventional sulphide flotation treatment in the presence of an activator such as copper sulphate to selectively float the sulphides in the concentrates. |
