However, extracting gold from quartz vein gold ore is a meticulous process that requires careful planning and execution. 1. Cyanide gold extraction includes crushing, leaching, filtering, adsorption, elution, etc. The first step in the method is crushing the quartz into small pieces. This can be done using a jaw crusher or a mortar and pestle.

1. Introduction. At present, more than 35% of China's gold resources (with a total amount of more than 1,000 tons) are difficult to be exploited and smelted, and about 700 tons of gold ores with high arsenic, antimony or sulfur are difficult to be directly cyanide leached (Lei et al., 2016).However, as the gradual depletion of easy-to-treat …

Arsenic-containing antimony gold concentrate (As-Sb-Au ore) is an important raw material for antimony and gold extraction [1–3]. Antimony often exists in the form of stibnite and usually needs to be removed before gold extraction [4–7]. Zhang et al. [8] proposed a slurry electrolysis (SE) method to pretreat this As-Sb-Au ore.

The pyrite contains 43.36% Fe and 41.26% S. The occurrence of gold in the different phases of the sulfide refractory gold ore is shown in Fig. 2, which indicates that 93.94% Au is encapsulated, especially, sulfide-encapsulated gold up to 80.85%. The X-ray diffraction (XRD) pattern of the sulfide refractory gold ore and pyrite is shown in Fig. 3.

The ore contains mostly free gold but some is refractory gold in pyrite, arsenopyrite and aurostibite. I am only looking to recover the free gold at this stage. I have tried water separation but it is slow and cumbersome to pan or run over my miller table and I am losing an unacceptable amount due to the fineness of the crushed ore (<75micron).

paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots. The two deposits are similar in mineral composition and alteration of surrounding walls. Therefore, it is feasible to compare the ore-forming factors of the two deposit. 1.

A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33% Sb in the form of antimonite. 24% Si in the form of quartz, small quantities of Pb, Fe, Cu, and Ni as well as 63 g/t gold, 60% of it as visible gold.
