Ore dressing combination reagent for rutile and ore dressing method of reagent

Abstract

The invention provides an ore dressing combination reagent for rutile. The reagent comprises a collecting agent, the collecting agent is phenyl amino acid, a pH value modulation agent, an activating agent, an inhibitor and a foaming agent are further included, and through the technical scheme, the reagent has the beneficial effects that the amino acid rutile collecting agent is adopted, and is poisonless and harmless, green and environment-friendly. The phenyl amino acid is adopted to serve as the collecting agent, the collecting capacity and the selecting capacity of rutile are high, and efficient separation of rutile and gangue mineral in the actual ore flotation can be achieved. The phenyl amino acid is adopted as the collecting agent, in combination with the pH value modulation agent, the activating agent, the inhibitor and the foaming agent, the rutile is subject to ore dressing, the proper matching is adopted, concentrate products with high TiO2 grade and the high recycling rate can be obtained, and the ore dressing effect is far better than that of the prior art.

Description

technical field [0001] The invention relates to the field of mineral processing technology, in particular to a rutile mineral processing combined reagent for rutile flotation and a mineral processing method thereof. Background technique [0002] Rutile is the mineral with the highest titanium content in nature, and it is the main raw material for extracting titanium metal, producing titanium dioxide and titanium dioxide materials with photocatalytic properties. my country's primary rutile mines account for 86% of natural rutile resources. Primary rutile resources are rich in reserves, but most of them are low-grade ores with finer particle size distribution, close intercalation relationship, complex mineral composition, and similar surface properties between useful minerals and gangue minerals. Therefore, the primary rutile ore in my country cannot adopt the combined process of gravity separation, electric separation and magnetic separation commonly used abroad. The flotati...

Problems solved by technology

Although fatty acid collectors are cheap, low in toxicity and strong in collecting ability, they have poor selectivity and are rarely used in flotation rutile; benzyl arsinic acid is the most typical rutile arsinic acid collector. Good performance, but expensive, high toxicity, and low solubility, some domestic rutile beneficiation plants still insist on using this kind of collector, but with the stricter and stricter environmental protection requirements and pressure year by year, arsine acid collectors are also gradually stopped Use: Styrene phosphonic acid is a typical rutile phosphonic acid collector, with good selectivity, strong collection capacity, and lower toxicity than arsinic acid collectors. It has long been regarded as a substitute for arsinic acid collectors Collector

However, it is expensive and highly corrosive to equipment. At the same time, phosphonic acid collectors have poor selectivity to calcium-containing gangue minerals. When the calcite content in the raw ore is too high, its use effect is not good; rutile hydroxamic acid Collectors are divided into alkyl (C 7～9 ) and benzene rings

The former has good collection performance and certain foaming performance, but its selective performance is weak; the latter has good selectivity and low toxicity, but its collection ability is weak and expensive
