Description
Technical Field
The invention relates to a reinforced activation flotation method for carbonate copper oxide ores, and belongs to the technical field of mineral processing.
Background
Copper is one of the earliest metals found and used by humans, and copper and its alloys are widely used in the fields of energy, traffic, electricity, etc. due to their excellent electrical conductivity, thermal conductivity, wear resistance. Copper smelting raw materials still mainly comprise copper sulfide ores, however, with the continuous promotion of global industrialization progress, the contradiction between copper resources and copper material supply and demand is continuously aggravated, and the copper sulfide ores are difficult to meet the increasing copper resource demands. Copper oxide ore is one of important copper ore resources, and efficient development and utilization of copper ore is certainly an important supplement to copper metal resources, and is also an important research direction of mineral processing workers.
At present, carbonate-type copper oxide ore (malachite and blue copper ore) is the copper oxide mineral with the most wide distribution, and aiming at the recovery of the mineral, the most widely applied method in industry is a sulfide-xanthate flotation method, namely Na is adopted 2 S, naHS and other vulcanizing agent pairsThe surface of the carbonate copper oxide ore is modified to generate a copper-sulfur compound film with stronger hydrophobicity, and then the film is recovered by adding a xanthate collector. In recent years, some organic chelating agents have high metal ion chelating ability and high selectivity, and are also used for activating complex and difficult-to-separate copper oxide ores, such as D2, 8-hydroxyquinoline, triethanolamine and the like, wherein D2 has the advantages of small dosage, high flotation speed, high adaptability and the like, and has been used in industrial production.
2, 5-dimercapto-134-thiadiazole (bismuth reagent for short in Chinese and DMTD for short in English) is a main active ingredient of D2, white to light yellow crystal powder is commonly used for detecting bismuth, copper, lead, palladium and antimony, and particularly can react with copper to generate brown precipitate. Bismuth reagent is excellent activator of carbonate type copper oxide ore, and can improve flotation recovery rate of carbonate type copper oxide ore by about 50% in order to be successfully applied to industrial production. However, the bismuth reagent has a narrow dosage range, copper oxide ores are difficult to be activated effectively when the dosage is low, and flotation recovery of the copper oxide ores can be inhibited seriously when the dosage is high, so that production cannot be carried out normally. Although theoretical researches show that the method adopting solid-liquid separation can improve the problem that excessive bismuth reagent inhibits copper oxide ore floatation to a certain extent, the method cannot be applied to industrial production in view of environmental protection, cost and other problems. Therefore, the activation process of the carbonate type copper oxide ore is studied deeply, the state of the activation product on the surface of the mineral is regulated and controlled directionally, the activation effect of the activator is enhanced, the dosage range of the activator is widened, and the method has great significance to industrial production.

The copper content of the copper oxide ore in the step (1) is 0.5-4.5% by mass.
And (3) adding 100-500 g of regulator, 100-500 g of activator, 50-400 g of collector and 20-80 g of foaming agent into one roughing operation of the step (2) per ton of copper oxide ore.
