DESCRIPTION LU505722
FLOTATION REAGENT AND FLOTATION METHOD FOR MARMATITE AND
JAMESONITE
The subject application relates generally involves mineral processing, and in particular to a method for separating marmatite and jamesonite.
The separation of marmatite and jamesonite is the most common in mineral processing. Due to the difference in floatability between them, the separation process is mostly used to depressant the flotation of lead minerals from zinc minerals. In order to obtain qualified concentrate, zinc minerals must be removed from lead concentrate.
The main depressants of marmatite are cyanides, sulfides and sulfur oxides (sulfites). These are inorganic agents, which generally have the problems of poor selectivity and large dosage, and some are even highly toxic. Therefore, it is particularly important to develop a new depressant with high selectivity in the flotation separation process of marmatite and jamesonite. Organic depressants have different bonding abilities with different metal atoms because of their specific functional groups, which points out the direction for the efficient separation of lead and zinc.
SUMMARY LU505722
In order to effectively separate marmatite from jamesonite, the invention provides a flotation reagent and a flotation method for marmatite and jamesonite, which adopts an organic reagent as a depressant and has the advantages of strong selection and low dosage, and can realize the separation of marmatite and jamesonite at the natural pulp pH value.
The technical scheme of the invention is as follows: a flotation method for marmatite and jamesonite adopts one of nitrilotriacetic acid, Congo red dye, thioglycolic acid or thiourea as marmatite depressant, and adopts a separation process of inhibiting the flotation of lead minerals from zinc minerals, comprising the following steps: (1) Grinding lead-zinc ore containing jamesonite and marmatite, in which the content of-0.074 mm particle size is 80-95 %, and the pulp concentration is adjusted to 30-40 %. (2) Nitrilotriacetic acid, Congo red dye, thioglycolic acid and thiourea were prepared into 10 % solution in a stirred tank. (3) Ammonia triacetic acid of 500-1000 g / t was added to the slurry, and then collector and foaming agent were added. After mixing, flotation was carried out to obtain lead coarse concentrate. (4) The obtained lead coarse concentrate cleaning for three times, and the addition amount of the first, second and third depressants is reduced by half in turn on the basis of rough cleaning, and the middles obtained in the above steps returns to the previous operation in turn, with the action time of all depressants being 6min, and the action time of sodium diethyldithiocarbamate and foaming agent being 3min and 1min respectively.
In step (3), 300-900 g/t of Congo red dye is added into the pulp to be selected, then sodium diethyldithiocarbamate and foaming agent are added, and lead coarse concentrate is obtained by flotation after pulp mixing.
In step (3), 100-300 g/t of thioglycolic acid is added into the pulp to be selected, then sodium diethyldithiocarbamate and foaming agent are added, and lead coarse concentrate is obtained by flotation after pulp mixing.
In step (3), 300-900 g/t of thiourea is added to the pulp to be selected, and wheru505722 thiourea is used as an depressant, half of sodium diethyldithiocarbamate is added on the basis of roughing for the first, second and third beneficiation, then sodium diethyldithiocarbamate and foaming agent are added, and then lead coarse concentrate is obtained by flotation after pulp mixing.
The adsorption of the depressant on the surface of marmatite is stronger than that on the surface of jamesonite, which makes the surface of marmatite hydrophilic and further promotes the flotation separation of marmatite and jamesonite.
The invention has the following advantages: (1) The inhibitor can selectively inhibit marmatite at natural pH, and the dosage is low, so it can be widely used in lead-zinc separation. (2) The inhibitor is simple in preparation, easy to dissolve in water and convenient to operate.
The technical scheme of the present invention will be further explained in detail through specific examples.
