Abstract

The invention relates to a collophane low-temperature reverse flotation collector and a preparation method thereof. The collector is prepared by mixing basic substance with water in a weight ratio of 1:20-100, wherein the basic substance comprise the following components by weight percent: 90-95% of higher fatty acid soap with the fatty acid content of no less than 40% and 5-10% of terpenol. The collector is characterized in that the grade of the selected crude ore is low, the applicable scope is wide, the recovery rate of the concentrate is high, the MgO content of the concentrate is low and the cost of ore dressing is low. Compared with the prior art, the gelation of the collector is difficult to appear below 10 DEG C, the flotation index is qualified and the collector can adapt to the low-temperature flotation.

Description

technical field [0001] The invention relates to a collophosite low-temperature reverse flotation collector and a preparation method thereof. Background technique [0002] Phosphate rock is an important strategic resource, mainly used in the preparation of phosphate and phosphate fertilizer. The production of phosphate and phosphate fertilizer requires the raw material of phosphate rock to be P 2 o 5 The higher the content, the lower the MgO content, the better. General high-quality phosphate rock P 2 o 5 The content is above 32%, and the MgO content is below 1%. In nature, there are limited phosphate rocks that can reach such an index, and most low-phosphorus and high-magnesium phosphate rocks need to be beneficiated in order to meet the requirements of high-quality phosphate rocks. At present, the collectors used in the flotation beneficiation process have a relatively good separation effect at room temperature. However, when the water temperature is lower than 10°C,...
