Xinhai Mechanical Design Institute focuses on the design and research of mineral processing equipment for over 20 years, who has required numerous technical achievements in the ball mill, the combination of KYF flotation cell and XCF flotation cell and updated high-efficiency thickener.
Recently, Xinhai Mining with mineral processing EPC+M+O service successively appeared the 4th China Copper Industry Science and Technology Development Exchange Conference and China Cyanide Tailing Dealing and Comprehensive Utilization Technology Exchange Conference. Xinhai discussed the technology development result with peers and constantly increasing industry influence.
The gold gravity separation refers to separate useful minerals and gangue through the difference in mineral density with the aid of the combined forces of the medium fluid and various mechanical, which is mostly used to recover the placer gold and coarse-grained gold (difficult to recover by other methods).
In the actual production, which kind of gold ores are suitable for the flotation process? And what are the common gold flotation processes?
Carbon in leaching(CIL process) is one of the main methods of gold beneficiation, which adds activated carbon to the slurry while leaching and adsorbing gold.
According to different ore properties, the copper-lead-zinc sulfide ore flotation processes are also different, mainly including preferential flotation process, full mixed flotation process, partial mixed-preferential flotation process and iso-flotation process.
According to the mineral properties, the nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, which have the different nickel extraction methods.
Limonite is a weak magnetic mineral, as refractory iron ore. It doesn’t have obvious different from density, magnetism, and floatability. In this passage, let’s learn about the common processing methods of refractory iron ores.
At present, the common tailings reprocessing technologies mainly include flotation method, gravity separation method and magnetic separation method. Different tailings reprocessing technologies means different tailings reprocessing equipment.
Compared with lead-zinc oxide ore, the composition of lead-zinc oxide ore is more complex, with many associated minerals, and the particle size is finer. It is easy to produce sludge and contains a lot of soluble salts. Various reasons make the flotation treatment of lead-zinc oxide ore difficult. This article will introduce you to 5 flotation methods and teach you how to choose lead-zinc oxide ore.
Carbon leaching method for gold extraction (CIL) means the activated carbon is added into the pulp, and leaching and adsorption of gold are carried out simultaneously.
At present, the common recycling and utilization of gold tailings mainly include the recycling of gold, the recycling of other associated non-ferrous or ferrous metals, and the recycling of non-metallic minerals.
Quartz sand extraction is a difficult extraction technology to remove a small amount of or microscale impurities in quartz sand and gain refined quartz sand or high purity quartz sand. In this passage, we will introduce several quartz sand extraction methods.
Due to the different ore properties of all kinds of vein gold ore, the extraction processes of vein gold are also different. The five extraction processes of vein gold mainly include single flotation process, all-slime cyanidation process and the combined gold extraction processes composed of gravity separation, flotation and cyanidation process.
