Problems solved by technology

[0012] In the methods disclosed above, the flotation for sesquioxides is mostly positive flotation. When cationic reverse flotation is used to remove sesquioxides, mechanical desliming, flotation desliming, and gravity desliming are basically carried out in advance. Solve the problems caused by fine particles such as large dosage of cationic reverse flotation reagents, poor sorting performance, and high foam viscosity

Abstract

The invention provides a mineral processing technology for removing sesquioxide from collophanite through intermediate grading retreatment. The mineral processing technology comprises the following steps: grinding collophanite, mixing graded overflow with a sesquioxide removal agent, and carrying out reverse flotation roughing to obtain rough concentrate and rough tailings; grading the rough concentrate to obtain fine-fraction concentrate and coarse-fraction concentrate, and scavenging the rough tailing to obtain sesquioxide-removed tailings and scavenged concentrates; and combining the coarse-fraction concentrate and the scavenging concentrate and then conducting mixing with a sesquioxide removal agent for reverse flotation re-separation, returning re-separation tailings to ore grinding for closed-loop circulation, combining the re-separation concentrate and the fine-fraction concentrate, conducting reverse flotation operation for removing carbonate gangue, and then obtaining final high-quality concentrate. According to the method, the problems that positive ion reverse flotation froth is sticky and the selectivity is poor due to the fine fraction can be effectively solved, meanwhile, under the condition that the phosphorus concentrate index is guaranteed, the phosphorus pentoxide recovery rate is increased, the ore grinding energy consumption is reduced, and the scientific and economical industrial implementation technology for removing sesquioxide through collophanite positive ion reverse flotation is provided.

Description

Technical field [0001] The present invention is in the field of phosphate rock beneficiation, mineral relates to a process for the removal of phosphate rock flotation cationic counterion sesquioxide, and in particular relates to a coarse grinding and then classifying the intermediate foam treatment to improve cationic, advanced extraction qualified fine mine, reduce energy consumption and improve the yield of sesquicarbonate oxide removal process. Background technique [0002] Collophane of resources are mainly distributed in Hubei, Yunnan, Guizhou, as the effective use SimpleChoice calcium phosphate rock mining continues, the oxide high-powered semi collophane imminent. But iron-containing minerals and aluminosilicate minerals disseminated fitted state complex and fine particle size distribution, a high positive flotation costs, refractory backwater, cationic reverse flotation froth viscosity, poor selectivity, severely restricted the class of phosphate the effective development...
