<p>The present invention relates to a method of controlling the variation in content of minerals that float naturally in the feed of a concentration plant flotation circuit processing valuable minerals, such as minerals containing precious metals, copper-, nickel- and zinc-bearing minerals. After grinding, rough flotation is performed on minerals that float naturally, such as talc, into what is termed rough talc concentrate, which is then stored. The rough talc concentrate is fed into the valuable minerals flotation circuit as a pre-defined feed, and as a result the control of the flotation circuit is improved and reagent costs are substantially reduced.</p> |
