Evaluación del Factor ORG con mineral de mina en el Condominio Sur, Nambija

Abstract

The objective of this research is to determine the E-ORG factor (gravimetrically recoverable gold) using the mine material of the Nambija-Condominio Sur mining district, applying this method as an alternative to the traditional methods used by artisanal miners that are not efficient And pollute the environment by the use of mercury. For this, an experimental test was performed using the Knelson KC-MD 3 concentrator following the procedure standardized by Professor LAPLANTE 1996, which consisted of three stages of progressive grinding and sequential recovery, under the following parameters: 1PSI water pressure, Water 3.5l / m and rotation force 60Gs. The mineral used for the test is a skarn whose specific weight is 3.28 g / cm3 with a mineralogy of garnet (69%), pyroxene (12%), quartz (10%), calcite (7%), apatite ) And opaque (1%) and with gold law of 2.68gr / Ton. We performed two tests in which we obtained an average recovery of 79%, obtaining more gold release in the first stages of the test with a relatively thick material.
