Description

где J - алифатический Cs-Ci8 углеводородный радикал. Условное название реагента АВ-3. Собиратель хорошо растворим в воде, нечувствителен к сол м жесткости. По данным токсикологических и дерматологических испытаний это соединение не токсично (ЛД 5000 мг/кг живого веса) и не раздражает кожу при многократном воздействии I-5%-ных растворов. Пример. Руду, содержащую 2,5% п тиокиси фосфора, 57% кальцита и 3% доло .лшта, измельчали до крупности 50% - -0,2 мм и подвергали основной флотации и двум перечисткам. Основную флотацию проводили во флотом а шине ФМ-1 с камерой емкостью 1 л (число оборотов импеллера 1800 об/мин) при :4. В качестве регул тора использовали жидкое стекло, крахмал, сложный депрессор, в качестве собирателей - омыленную жирнокислотную фракцию таллового масла (ЖКТМ), шведский реагент Lilaflot OLP-40 и предлагаемое соединение - амфотерное ПАВ типа бетаинов (АБ-3).where J is the aliphatic Cs-Ci8 hydrocarbon radical. The conventional name of the reagent is AB-3. The collector is well soluble in water, insensitive to salts of hardness. According to the toxicological and dermatological tests, this compound is not toxic (LD 5000 mg / kg of live weight) and does not irritate the skin with repeated exposure to I-5% solutions. Example. The ore, containing 2.5% phosphorus pentoxide, 57% calcite and 3% dolosh, was crushed to a particle size of 50% –0.2 mm and subjected to main flotation and two cleanings. The main flotation was carried out in a fleet and on an FM-1 tire with a 1-liter chamber (impeller revolutions 1800 rpm) at: 4. Liquid glass, starch, a complex depressor were used as a regulator, saponified tall oil fatty acid fraction (GHTM), Swedish Lilaflot OLP-40 reagent and the proposed compound — an amphoteric surfactant of the betaine type (AB-3) were used as collectors.

Claims

3. For the number of 2418556, cl. In 03D 1/02, 1977, Pi of which the decision was made to issue an author's certificate. The collector was fed into the pulp in the form of a 1% aqueous solution. The cleanings were carried out without peareH: toB in a 0.5 liter chamber at pH 10. The collector of AB-3 provides for obtaining concentrates with a content of 26-36% P2O5 with a rather high recovery - 69-79%, whereas with the most effective of the known reagents - Lilaflot OLP-40 - the content of phosphorus pentoxide in concentrates is 1.5-2.0 times lower. This indicates a higher selectivity of the AB-3 reagent during the flotation separation of apatite and carbonate minerals. The use of AB-3 reagent allows the use of poor high-carbonate apatite-containing ores in processing, which significantly expands the raw material base for the production of phosphate fertilizers. Thus, an advantage of the invention is to increase the selectivity of the flotation process of apatite from ores. Claims The use of an amphoteric surfactant of the formula
