Currently, Caserones Mine concentrator plant processes more than 4,000 tons per hour of sulfide ore with an average grade of 0.36 % of total copper to produce between 110,000 and 180,000 tons per year of copper in concentrate. The ore that feeds this plant comes from the mine and from available stocks, which presents considerable variability in terms of mineralogy, with fluctuations in the content of copper sulfides and oxides, pyrite, clays and other species. This condition generates impacts on the flotation-thickening process and, therefore, requires the application of adjustments in the operational strategy to avoid adverse effects on copper production.
Technological solutions are sought to identify and quantify the mineralogical species present in both the ore and gangue that feed the concentrator plant. The solutions must provide on-line information on the mineralogical composition of primary and secondary copper sulfides, oxides and clays, among others.
The minerals that feed the concentrator plant have a variable mineralogy, with changes in the content of copper sulfides and oxides, pyrite, clays and insolubles, among others.
Eventually and unexpectedly.
On-line mineralogy analyzers have not been tested.
As part of the background evaluation process, the following will not be considered:
