Note The metal ores are mostly rows which are suitable for extraction. The process of removing unwanted minerals from the ore is known as ore concentration. It is also known as ore dressing or ore benefaction. The process of crushing the smaller piece into fine.
Sep 30, 2021 The direct priority flotation process is adopted to extract copper from disseminated sulfide ore, and the process flow is shown in the figure below. Because the amount of inhibitor used in copper extraction is small, only a small amount of activator is needed when separating sulfur, and sulfur can be extracted even without adding activator.
Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2 ). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
A copper-lead dressing plant in Xinjiang the ore with the close symbiosis and fine particle distribution, the process the plant adopted leaded to the poor concentrate grade. So Xinhai was authorized to reform the technology. After analysis of crude properties, Xinhai decided to adopt parts of the preferential flotation process.
