Definitions
- the present invention relates to the enrichment of ores by flotation with organic collectors, constituted by thio compounds. More specifically, it targets the processing of ores based on heavy metal oxides and sulfides.
- Alkyl polysulfides have been proposed, in the same way as alkylnaphthalenes, alkyl- and chloroalkyltetralins, or mercaptans, as additives to the flotation collectors constituted by amines with a long aliphatic chain, in particular C 7 at C t g or more. If by this means - according to US-A-3,059,774, we can save some of the expensive amines, there is still no question of being able to replace them completely.
- the present invention is based on the discovery that the collecting properties of a thio compound can be intensified by a certain accumulation of sulfur atoms in the molecules of these compounds.
- dialkyl polysulfides can give better results than the corresponding mercaptan; this is surprising theoretically, since polysulfides have a molecular structure with two lipophilic chains. This fact is all the more unexpected since the alkyl polysulfides with more C a are even less soluble in water than the mercaptans.
- the process according to the invention consists in carrying out the flotation of ores or minerals in the general manner known per se, but with at least one dihydrocarbyl polysulphide as collector, or jointly with a collector of known type other than a long-chain aliphatic amine, this or these polysulphides being represented by the formula where R and R ', similar or different, are alkyls or alkenyls which can carry substituents and x is a number with an average value of 2 to 8.
- the substituents of the hydrocarbon groups R or / and R ' can be other aliphatic, cycloaliphatic or aryl radicals, halogens, nitriles or of groups OH, -COOH, NO 2 , NH 2 , CONH 2 , esters or carbonyls.
- the substituents providing affinity for water are particularly favorable.
- the groups R and R ' are C 6 to C 18 linear or branched.
- a method of preparing such polysulphides which consists in treating, for example, the corresponding mercaptan with sulfur, in the presence of an amine as catalyst, according to the reaction:
- This process actually provides a mixture of polysulfides of different numbers of S atoms, where x is actually an average of these numbers.
- the polysulfides according to the invention are practically insoluble in water, they can be introduced into the ore pulp to be treated in the form of a solution in a solvent, in that of emulsion or extremely fine dispersion.
- a solvent in that of emulsion or extremely fine dispersion.
- the emulsion can be produced by mixing with a surfactant liquid such as polyethoxylated polyol or alkylphenol, petroleum sulfonate, polyalkoxylated mercaptan, a fatty acid ester of polyoxyalkylene or sorbitan, etc.
- the aqueous or other dispersion it can be obtained by wet micronization.
- the molar proportions of the new collectors, according to the invention, to be used in flotation are the same as those of the known technique, that is to say in general about 0.05 to 0.5, and more often of 0.1 to 0.25 moles per tonne of ore.
- a series of flotation tests is carried out on copper sulphide ore from the South African mine at Palabora, with a Cu content of 0.45 to 0.48%. 600 g of this ore are ground to a fineness such that 76% of the powder passes through a 148 micron mesh sieve.
- the product After adding the necessary adjuvants, the product is subjected to flotation for 20 minutes at pH 7.5, in a 2.5-liter laboratory cell of the MINEMET M 130 type, in the presence of methyl-isobutyl carbinol as a foaming agent. , added at a rate of 25 g per tonne of ore.
- the collectors are introduced in the form of mixtures of 57.5% by weight of thio compounds with 42.5% of surfactant, nonyl phenol polyoxyethylene, known commercially under the trademark "SIMULSOL 730".
- surfactant nonyl phenol polyoxyethylene, known commercially under the trademark "SIMULSOL 730".
- examples 1 and 2 usual mercaptans in flotation and, on the other hand, (examples 3 to 6) polysulfides according to the invention; their proportion, in millimoles per tonne of ore, is indicated in the Table of results, which follows.
- the Cu concentrations obtained are always higher, with the polysulphides, than those given by conventional collectors.
- the pentasulfides allow a copper recovery comparable or superior to that of the mercaptans.
