Description

(54) COLLECTOR FOR FLOTATION OF NESULPHIDE ORES

; .. one

This invention relates to the field of the reprocessing of wetland flotation.

It is known that in a series of enrichments of ores, sulfo carboxylic acids are very effective collectors, using -. Available both independently and in conjunction with other collectors 1.

Osulfo carboxylic acids 2 are used for this purpose.

However, not in all cases their use allows to obtain rather high technological indicators of enrichment.

The following compounds are known: 0-alkyl-with sulfo-15-booms of the general formula or their water-soluble salts, obtained by sulfonating o-alkyl-substituted carboxylic acids and not previously used in fleets.

The aim of the invention is to increase the technical; nological indicators of flotation of non-sulfide ores.

The goal is achieved by using as a collector (X-alayl-o-sulfo-carboxylic acids of the formula

R I H (C% CH2) / g -

CHOZN

where R is an aliphatic hydrocarbon radical with the number of carbon atoms from

: 1 to 5; p 1-3, or their water-soluble salts.

The reagent was tested during flotation of a number of non-sulfand ores.

Example 1. Floated barite ore with a barite content of 11%.

Liquid glass 1 kg / t and soda 0.5 kg / t were introduced into the ore pulp. After that, 20 ore flotation was carried out with three perekischalky foam product. The resulting product is barite jKOHyeHTpaT. I. The cost collector was 100 g. 3; ; . ; 73, The recommended collector in comparison with the known ones allows to increase the extraction of barite into concentrate by 2.7-5.7% while improving the quality of the concentrate m 4.0-10.0%. Example 2. Gravitational enrichment of IlbiaMbi for cassiterite ore is treated with 0.5 kg / ton of alkyl-a-sut-carboxylic acid. Aminohydroxamic acid — 50 g / t, hydrochloric acid to pH 3–33, and pine oil — 20 g / t are then introduced into the pulp, and a rough flotation concentrate is obtained, which is subjected to four scrubbing at a pH of 1.5-2 with addition to each of these, 15 g / t of the above L-alkyl-L-sulfo carboxylic acids were obtained. As a result of the implementation of the process, compared with the action of public collectors, the quality of the concentrate increased by 2.7-4.1% and the extraction of tin by 7-8%. Example 3. Tails of magnetic segmentation of iron ore in hard water are treated with soda-I kg / t, idar glass - 0.6 kg / t, and a mixture of potassium salts of L-alkyl-L-sus carbohydric acids in the amount of 03 kg / t and saponified raw taltovym oil - 0.5 kg / t. The flotation of low-grade minerals, iron fishing, and two cleaning of the froth product is carried out with the addition of 0.1 kg / ton of liquid glass to each of them. The use of the recommended reagent contributes to a 43% increase in iron recovery in the concentrate while maintaining the quality of the concentrate. .. Thus, the main advantage of this invention is to improve the technological performance of the flotation of non-sulfide ore -, - Formula of the invention The use of 0-alkyl-0 {-sulfocarboxylic acids formul:.
