The presence of copper sulphides in the ore reacting with cyanide requires oxygen similar to gold, according to Elsners equation. If the ore has 7 ppm Au and 460 ppm copper then it is not hard to see the effect on the oxygen demand. Oxygen sparging will assist, however if the oxygen level drops then the leach kinetics will be affected.

Zinc powder replacement equipment is a system that uses zinc powder to extract gold from your solution. Processing capacity ≤ 1200m ³/ d。. The device is mainly aimed at the gold ore with more silver. After purifying and deoxidizing the precious liquid, the zinc powder replacement device is added, and then the gold slime is obtained.
Ore sorting is a preconcentration process that improves the head grade of the feed to the concentrator. Separating out gangue and low-grade ore at the earliest opportunity optimizes downstream processing. Successful ore sorting also reduces variability in the feed, and delivers more value to the concentrator on an hourly basis.
A prominent iron ore mine in Australia faces the challenge of processing a staggering 50 million tons of material annually. In response to significant dust concerns raised by the state regulator, the mine sought an effective solution for addressing these issues. DSI, a renowned provider of dust control solutions, was engaged to devise ...
DMS Process Solution. Among them, a commonly used equipment for the DMS process is a dense medium cyclone (DMC), which can separate dense media according to the difference in specific gravity. 1. Crushing: The material is first crushed to a smaller size to facilitate the release of valuable minerals from the gangue. 2.
The upper limit of the ore particle size is related to the ore size, embedding characteristics, and equipment size. In usually, the ore is 50-150mm, and the coal is 300-500mm. DMS can greatly reduce the surrounding rock and waste rock under the same processing capacity, reduce ore grinding consumption, thus reduce production costs.
