Problems solved by technology

[0004] High-purity zircon is separated by gravity separation, magnetic separation, electric separation and other processes. Due to poor separation accuracy of equipment, Zr(Hf)O in zircon concentrate 2 content is difficult to reach 65%
Even concentrate Zr(Hf)O 2 The content can reach 65%, but more recovery rate will be lost, resulting in waste of resources
The conventional zircon collectors oleic acid and sodium oleate have poor selectivity, and it is difficult for the concentrate to meet higher quality requirements

Abstract

The invention discloses a zircon beneficiation composite reagent and a beneficiation method. Each ton of reagents for adding to crude ore comprises, by weight, 100-2000 g of sulfuric acid, 0-500 g of inhibitors and 100-1000 g of collecting agents. The inhibitors are sodium silicate, the collecting agents comprise petroleum sodium sulfonate and hydroximic acid, and a mass ratio of the petroleum sodium sulfonate to the hydroximic acid is 1:1-10. The zircon beneficiation composite reagent and the beneficiation method has the advantages that the zircon beneficiation composite reagent is good in zircon collecting property and selectivity, and the grade and the recovery of zircon concentrate can be further improved; the sodium silicate can be added to materials to be used as the inhibitors for fine silt or clay minerals when the materials contain few fine silt or clay minerals during flotation operation.

Description

Technical field [0001] The invention belongs to the technical field of mineral processing, and specifically relates to a zircon beneficiation combination agent and a beneficiation method. Background technique [0002] The zircon is zirconium orthosilicate and the chemical formula is ZrSiO 4 , Is the most common kind of zirconium-containing minerals. Zircon deposits are mostly seashore placers, and heavy minerals such as magnetite, ilmenite, rutile, monazite, etc. are usually co-existed in heavy sands containing zircon. my country’s proven zircon ore reserves rank 5th in the world. Zircon is a very important non-metallic mineral resource. It is mainly used as a raw material for zirconate refractory bricks, and can also be used for precision casting sand and ceramics. appliance. [0003] Common ore dressing methods: gravity separation, magnetic separation, electrostatic separation and flotation are often used. Gravity separation is based on the difference in mineral density. The hea...
