201751 · The chemical composition of the ore is given in Table 1. Before the experiments, the ore was dried at 383 K, and then ground and sieved to obtain a particle size below 74 μm. The main phases of the material were analyzed by XRD (Fig. 1). Many mineral components are observed in the refractory gold ore, including quartz (SiO 2), …

Cyanide has a natural tendency to bond with metals, even when they occur in microscopic amounts, such as gold and silver in ore. This method of gold recovery has been popular for over a century. Advances in

At higher pH values, higher levels of antimony pentoxide have been observed on gold surfaces, which then inhibit gold extraction (Young and Luttrell, 2012).
