Abstract

The invention discloses a beneficiation reagent for tin flotation of tin ore. The beneficiation reagent is prepared from the following raw materials in parts by weight: 20 to 30 parts of alkyl phosphate, 20 to 25 parts of sodium carbonate, 20 to 30 parts of sodium phosphide, 35 to 45 parts of 3, 3-dimethyl butyric acid, 15 to 23 parts of phosphorus, 10 to 25 parts of hydroxybutyl ethylene, 35 to 50 parts of 3-amino-2-butenoic acid, 4 to 5 parts of quick lime and 12 to 15 parts of an activating agent. The beneficiation reagent has the characteristics of high grading efficiency, high yield, small dosage, simple and reliable process flow, easiness in operation and the like, and is suitable for being applied to re-sulfuration and mixed tin ore beneficiation.

Description

technical field [0001] The invention relates to the field of mineral processing technology, more specifically, to a mineral processing agent for tin ore flotation and a preparation method thereof. Background technique [0002] At present, the mineral raw materials for dressing and smelting tin ore in my country are mainly sulfur tin ore, tin copper ore, sulfide and mixed tin ore. The tin ore beneficiation method is mainly the flotation method, and sometimes in order to improve the quality of the lead concentrate and remove impurities, the tin concentrate is then subjected to chemical beneficiation. [0003] The dominant collectors in the tin ore flotation process are xanthate, thiophosphate and mercaptan, thiamine ester, xanthate, black drug ester, xanthate and other flotation agents, but in actual In the beneficiation, most of the results cannot meet the design requirements, and the recovery rate of tin concentrate is low, resulting in a waste of mineral resources.
