Abstract：Flash flotation is a mineral processing technique used in grinding and classification circuit to recover valuable minerals from the cyclone underflow. The technology is essential for reducing the over-grinding of target minerals and realizing early recovery. This paper summarizes the ore processing conditions applicable to flash flotation technology. If there is a certain amount of target minerals with high dissociation degree in the settling sand,and the grade of the target minerals is higher than that in the overflow,or if it is found through tailings analysis that the loss rate of fine-grained metals in the tailings is high,that is,the minerals have been over ground,or if the natural floatability of the target minerals is good,such as gold ore and graphite ore,it can be considered that flash flotation is suitable for the above ore conditions. Then it is analyzed in this article the factors that affect the effectiveness of flash flotation,including the properties of the ore itself,reagents and process parameters,flotation equipment operating parameters,etc.,all of which can affect the effect of flash flotation. The following introduces the expansion of flash applicable minerals in recent years and the research progress of flash flotation test methods. The most typical application is in the field of gold flotation where the "gravity reverse enrichment" effect is more pronounced. The BGRIMM Technology Group conducted continuous experiments on flash flotation of crystalline graphite,verifying that flash flotation has a certain protective effect on graphite flakes. Through conducting industrial experiments of flash flotation in lead-zinc and copper mines,the recovery rate of associated gold and silver in the ore has been significantly improved while ensuring that the recovery of target sulfide minerals is not affected. In terms of research methods,it is possible to qualitatively analyze the feasibility of flash flotation by exploring the presence of fast floating components in ores through batch-scale experiments. However,it is still impossible to evaluate the quantitative impact of flash flotation implementation on the entire process indicators in industry. The following summarizes the research and application progress of flash flotation equipment,with the largest equipment specification currently reaching 85m3. Among them,the YX series flash flotation machine developed by the BGRIMM Technology Group is currently the most widely used flash flotation equipment in industrial applications.Currently,the YX series flash flotation machines are widely used in gold,copper,lead-zinc,graphite mines and so on. Finally,it is proposed that with the increase of mine exploiting scale and the differentiation of ore properties,enlargement and specialization are the development directions of flash flotation equipment. With the continuous development of mineral resources,flash flotation technology has a very broad application prospect.
