Problems solved by technology

In the traditional zinc oxide ore "desliming flotation" process, the amount of desliming is very difficult to control accurately, the production is extremely unstable, and the interference of ore slime on zinc oxide flotation cannot be completely eliminated. In addition, desliming also removes Part of the zinc oxide minerals are destroyed, resulting in low recovery rate of zinc oxide, poor sorting index and other problems. In addition, traditional ore dressing agents require a higher operating temperature, and the general temperature requirement is greater than 25 ° C. For regions with lower temperatures or in winter (such as Yunnan high-altitude mining areas), flotation operations will not be possible

Abstract

The invention relates to a low-temperature-resistant zinc oxide ore flotation compound agent and a preparation method and application thereof. The compound agent comprises a compound regulator and a compound collector, wherein the compound regulator is composed of sodium hexametaphosphate, starch, humic acid Sodium is mixed in a weight ratio of 5~7:3~6:1~3; the composite collector is composed of octadecylamine, glacial acetic acid, sodium benzyl hydroxamate and waste oil in a weight ratio of 5~8:5~8 :1~3:1~3 mixed. The use of these two compound beneficiation agents eliminates the need for desliming in the flotation process, thereby enhancing the recovery of fine-grained zinc oxide, and the beneficiation recovery rate of zinc oxide ore can be increased by 5-15%.

Description

technical field [0001] The invention relates to the fields of mineral processing and comprehensive utilization of mineral resources and minerals, in particular to a low-temperature-resistant zinc oxide ore flotation composite agent and a preparation method and application thereof. Background technique [0002] Zinc oxide is negatively affected by high sludge content and soluble calcium and magnesium ions. In the process of "desliming and flotation" of traditional zinc oxide ore, it is very difficult to accurately control the amount of desliming, the production is extremely unstable, and the interference of the sludge on the flotation of zinc oxide cannot be completely eliminated. Some zinc oxide minerals are removed, resulting in problems such as low zinc oxide recovery rate and poor selection index. In addition, traditional mineral processing agents require higher operating temperature, generally higher than 25 °C. For areas with lower temperatures or in winter (such as Yun...
