Carlin-type deposits represent a major source of gold, and account for ~8% of the current global gold production (Muntean and Cline, 2018).Following the definition of the Carlin-type deposits in Nevada, similar ore deposits (Carlin-like) were reported in the Youjiang basin of SW China (e.g., Peters et al., 2007; Su et al., 2009a, 2018; Hu and …
E. General Discussion on Smelting.—Practically all of the shaft furnaces mentioned for the volatilization process are of the same type, except with minor differences in details as to the form of the grate- bottom and as to size. The ideal ore for treatment in such furnaces is one containing antimony from 15 to 25 per cent.; ore above 40 per cent.
Typically, gold is encapsulated or finely disseminated in refractory gold ores and the direct cyanidation is not effective for gold extraction from these ores, even after the ore is ground to exceeding small particles (Nazari, 2017, Corrans and Angove, 1991).Especially for sulfide refractory gold ores, in order to recover gold, many oxidation …
Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in …

For the recovery of New World silver, the Patio process was employed. Silver-bearing ore was ground and then mixed with salt, roasted copper ore, and mercury. The mixing was accomplished by tethering mules to a central post on a paved patio (hence the name of the process) and compelling them to walk in a circle through the mixture. The silver ...
The clean production process for extracting antimony from refractory gold ore involves sodium sulfide leaching, pressure oxidation, concentration, and crystallization steps. First, the stibnite in the refractory gold ore reacts with sodium sulfide, and antimony is dissolved into the leaching solution in the form of sodium …
As shown in Table 2, the slags are enriched in a variety of heavy metals and metalloids.Because As is always associated with Sb in antimony ore, the four wastes …
In nature, there is a small amount of the simple substance of bismuth. The most common bismuth minerals include bismuthinite (Bi 2 S 3), bismutite (Bi 2 O 3 or bismite), copper bismuthinite (3Cu2S·4Bi2S3), plumbum bismuthinite (2PbS·Bi 2 S 3), and so on, among which Bi 2 S 3 and Bi2O3 are of the highest value. The bismuth minerals …
The need for a new process to treat Broken Hill ore arose from the depletion of the secondary oxide ore that overlay the major sulfide mineralization. Natural oxidation to form the secondary zone had resulted in a concentration of silver and lead, and ore from this section of the ore-body could be smelted directly. ... These include antimony ...
