Flotación del mineral del sector La Pangui, en el distrito minero Chinapintza

Abstract

The present investigation work called “Ore flotation on sector La Pangui, at the district Chinapintza” has three stages, every one helps to get different metallurgical balances, the first stage include tests for grinding to obtain the desired grain size (84µm, 74µm and 67µm), after this the ore flotation process it is carried out, showing as the best the size of 84µm because of the mineral recuperation. The second stage, varies the pH values (8, 9 and 10) so the environment where is performed the flotation can change, just like the first stage, the flotation indicates the best mineral recuperation, in this case the pH 10 is the best environment for the mineral selection with a finally efficiency of 76.54%. The last stage varies the collector concentration (75g/ton, 50g/ton y 100g/ton) and the results indicate that, the best throwput is the flotation that works with the collector concentration 100 g/ton producing 76.54% mineral recovered. Accompanied these tests analyzing XRF was performed to determine the chemical concentration in each of the flotations.
