1. Single copper sulfide ore flotation reagent
The flotation of single copper sulfide ore is usually Performed in alkaline medium. Mainly use lime as adjuster, dosage: kg/ton. Flotation slurry, sometimes in order to strengthen the suppression of pyrite, can reach above. Lime can also precipitate heavy metal ions in the slurry, reducing the consumption of chemicals and the inhibitory effect on copper minerals. Lime has stronger inhibition on pyrite than caustic soda and soda, which is beneficial to improving the concentrate grade of copper ore flotation.
The commonly used collector is xanthate. In my country and the Soviet Union, butyl xanthate is the main one. In the United States, isopropyl xanthate is used more. Black powder is also a commonly used collector for flotation of single copper sulfide ores. Commonly used black drugs abroad include Hao, Hao, Hao, etc. The flotation effect of acetylamine produced in my country is also quite significant. Better flotation results can often be obtained by mixing black drug and xanthate, low-grade xanthate and high-grade xanthate, xanthate and other lipid collectors.
Except for pine alcohol oil, commonly used foaming agents are mostly used in the United States and mainly in the Soviet Union.
2. Copper ore flotation index
The flotation index of a single copper sulfide ore is higher, but the fluctuation range is larger. Generally speaking, coarse-grained quartz vein copper ore is the best choice, and the recovery rate can reach above %. Copper sulfide ore in copper-bearing sandstone deposits is also easy to select, and the recovery rate is also above %. The recovery rates of bornite and layered copper ores are low, about %. If factors such as the low raw ore grade or high oxidation rate of this type of ore are taken into consideration, it is still a good choice of ore. The flotation concentrate grade of a single copper sulfide ore is relatively high, generally around % copper, and it is not uncommon to have more than % copper.
The flotation recovery rate of a single copper sulfide ore in my country is extremely high, generally above %, with the highest reaching %. The concentrate grade is relatively low. However, in recent years, due to the implementation of the concentrate policy, the implementation of deficit dosing and the strengthening of production management, the concentrate grade has reached 10%, and the concentrate grade of individual dressing plants has reached %.
