Copper oxide ore is used to refine copper oxide. Copper oxide ore is produced in the Philippines, Pakistan and other regions. The monthly supply is about 1,000 tons to 2,000 tons. Copper oxide (CuO) is a black oxide of copper. The most common on the market today is 98% copper oxide and 99.95% copper oxide. The flotation method is still the main method for the treatment of copper oxide ore. According to the nature of the copper oxide ore and the nature of the collector used, the copper oxide ore flotation method is divided into direct flotation and stage vulcanization-flotation.
Copper exists mainly in the form of sulfide ore and oxidized ore in nature, the most important of which is sulfide ore, which is formed by the slow oxidative deterioration of sulfide ore. With the development of the defense industry, the electronics and electrical industries, and new technologies, the demand for copper is increasing, and although copper production is growing, it still cannot meet the needs. Copper resources are in short supply, and sulfide ore and copper-rich ore are decreasing. The mining grade of many copper mines abroad has dropped to 0.4%. Therefore, lean ore and a large number of difficult-to-select copper oxide deposits are in urgent need of development and utilization.The direct flotation method is the first method to use flocculant instead of sodium sulfide activation, including fatty acid flotation, amine flotation, neutral oil emulsion flotation and chelation collector. Flotation method, etc. It is suitable for copper oxide ore with simple mineral composition and uncomplicated properties. The direct flotation of complex copper oxide ore still has no breakthrough. Efficient selective collectors are especially important for direct flotation. In the early application of copper oxide ore flotation research, fatty acid salt was used as a collector for direct flotation, but this method is only applicable to ores with mainly malachite, simple gangue and high ore grade. The direct flotation method is applied earlier, but it lacks selectivity. So far, only the fatty acid flotation method has been applied to large-scale industrial applications. For decades, people have tried to develop a highly selective collector to float copper oxide minerals. Although some studies have achieved good results, they have not been widely used due to separation difficulties.
