Abstract:
Gold (I) sulphide is the inorganic compound with the formula Au sub(2) S. It is the principal sulphide of gold. It decomposes to gold metal and elemental sulphur, illustrating the nobility of gold. Recovering gold from sulphide refractory gold ore has been an important guarantee for the sustainable development of gold industry, while there are many challenges in the treatment of sulphide refractory gold ore, such as environmental pollution and low gold recovery. In this study we aimed at separating gold sulphide from Banded Magnetite Quartzite (BMQ) of Goa. The BMQ sample wasdried, powdered, concentrated by panning method and subjected to magnetic separation using neodymium magnet and sieved into different fractions with the sieve size of 250, 150, 106, 53 ?m. Powdered sample was tested for presence of gold sulphide by ICP-AES, SEM-EDX, CHNOS Analysis methods.
