Problems solved by technology

[0002] The main collectors used in domestic fluorite ore beneficiation are fatty acids, and oleic acid is commonly used. Oleic acid is an important collector for non-sulfide ore flotation, but the collector has poor water solubility and is sensitive to temperature. , poor selectivity and intolerance to hard water, large consumption, low concentrate grade and large index fluctuations, etc., especially in winter and when the water temperature in the northern region is lower than 15°C, the ore pulp needs to be heated during the beneficiation process, and even some northern beneficiation The pulp in the factory is heated all the year round, resulting in increased energy consumption and beneficiation costs, and serious environmental pollution. It is difficult to realize economical, efficient and clean development and utilization of fluorite ore resources; some synthetic collectors with good performance such as Medilan and AKK and nROX, etc., due to many synthesis steps, high cost, and some raw materials are not easy to obtain and difficult to use, so the utilization of fluorite ore resources urgently needs a collector with low temperature resistance, low cost and good collection selectivity
