Tara Minerals has announced the metallurgy recovery study results from the Champinon iron project. Arizona-based METCON Research carried out this study regarding a material from the project.
Recoverable magnetite was obtained in high level from these results. High magnetite levels enhance opportunity for maximized ore volumes and improve overall yields from the prospective project. Test results prove that extensive concentrations of iron are technically feasible to mine.
In addition, results showed that low-grades of iron ore can be focused through magnetic separation and crushing in order to produce an iron product of marketable grade. The results also validate that the high- and low-grade iron ores can be collectively processed. This maximizes crushing rates of ore tonnage while minimizing stripping ratios that can improve the economy of the project, considerably.
According to Steve Eady, Chief Geologist, these results have validated that the company has identified an important deposit for exploring and producing iron ore. The results have offered data that can help the company to optimize the potential of the project.
Francis R. Biscan, Tara Minerals’ CEO stated that these results give the necessary data in order to complete the preliminary mining plan and the required plant design to commence the production of salable iron ore at the project, besides validating the work that has been previously carried out. The company is expecting to communicate this progress to its shareholders.
The study utilized preliminary head grades of 52% and 41%. The magnetic concentrates had final iron grades of 68% and 58%, correspondingly at a 4 mesh grind size. The samples had final grades of iron concentrate of 68% and 67%, at a 10 mesh grind size.
