Изобретение относитс к гидрометаллургии цветных мет 1ллов и может быть использовано при перкол ционном и кучном вьщелачивании металлов из полиме- таллических и медных сульфидных и смешанных руд.The invention relates to hydrometallurgy of non-ferrous metals and can be used in percolation and heap leaching of metals from polymetallic and copper sulphide and mixed ores.
Целью изобретени вл етс снкжа- нне расхода кислоты и сокращение продолжительности процесса.The aim of the invention is to reduce acid consumption and shorten the process time.
Способ был опробован на укрупненной перкол дионной установке на которой моделируетс процесс кучного вьпцелачивани ,The method was tested on an enlarged percol dione unit on which the heap targetting process is simulated,
Размеры перкол тора: высота 0,7 м диаметр 0,17 м. В каждый перкол тор бьшо загрудсено 15 кг.руды, крупностью 20 мм, смешанной с органическим веществом . В качестве органического вещества использовали отходы обогати- тельных фабрик при обогащении полиметаллического сырь , содержащие керо- гены, битумы и алкилдисульфиды с эмпирической формулой Cj, Hj40NS3.Percolator dimensions: height 0.7 m, diameter 0.17 m. Each percolor was loaded with 15 kg of labor, 20 mm in size, mixed with organic matter. As an organic substance, wastes from enrichment plants were used in the enrichment of polymetallic raw materials containing kerogen, bitumen and alkyl disulfides with the empirical formula Cj, Hj40NS3.
Плотность орошени была прин та 70 л/т. После достижени определенной товарной концентрации металла в растворе проводитс ежедневный вывод 20% раствора и замена его свежим раствором .The irrigation density was accepted at 70 l / t. After a certain commercial concentration of the metal in the solution has been reached, a daily output of a 20% solution is carried out and replaced with a fresh solution.
Выщелачивание проводили на смешанной и сульфидной свинцово-цинковых ру дах и медной руде.Leaching was carried out on mixed and sulfide lead-zinc ores and copper ore.
В таблице приведен x пvIичecкий состав руды.. The table shows the x composition of the ore ..
Пример 1.(сульфидна свинцо- во-цинкова руда). 15 кг руды смешали с органическим веществом, вз тым в количестве 0,5% от веса руды, что составл ет 0,075 кг, и .загрузили в перкол тор. Дл выщелачивани использовали 0,1 н. раствор серной кислоты, приготовленньй на смеси рудничной и талой вод в соотношении 1:1. После каждого орошени в растворе определ ли содержа1ше цинка и серной кислоты . Перед каждым орошением кислотность раствора доводили добавлением серной кислоты до О,I н.Example 1. (sulfide lead-zinc ore). 15 kg of ore was mixed with organic matter, taken in the amount of 0.5% by weight of the ore, which is 0.075 kg, and loaded into a percolator. 0.1 N is used for leaching. sulfuric acid solution prepared on a mixture of mine and melt water in a ratio of 1: 1. After each reflux in the solution, the content of zinc and sulfuric acid was determined. Before each irrigation, the acidity of the solution was adjusted by adding sulfuric acid to O, I n.
Бьшо проведено 280 орошений. Концентраци цинка в растворе постепенно сш-шалась, начина с 22 г/л. Извле82280 irrigations were carried out. The zinc concentration in the solution was gradually cured, starting with 22 g / l. Removed82
чёние цинка составило 85,6%; РЪ - 68,а7%; Cd - 75,40%; Си -69,37%, расход серной кислоты - 2,09 т/т 2 Zn + РЪ.black zinc was 85.6%; Pb - 68, a7%; Cd - 75.40%; C -69.37%, consumption of sulfuric acid - 2.09 t / t 2 Zn + Pb.
Пример 2 (смешанна свинцо- во-цинкова руда). 15 кг руды смешали с органическим веществом, вз тым в количестве 4% от веса руды, что составило 0,60 кг, и загрузили в перкол тор . Дл выщелачивани использовали 0,01 н. раствор серной кислоты, приготовленный на смеси рудничной и талой вод в соотношении 1:0,9.Example 2 (mixed lead-zinc ore). 15 kg of ore was mixed with organic matter, taken in an amount of 4% by weight of the ore, which amounted to 0.60 kg, and loaded into a percolator. 0.01 n was used for leaching. sulfuric acid solution prepared in a mixture of mine and melt water in a ratio of 1: 0.9.
За 280 орошений извлечение цинка составило 69,80%; РЪ - 62,40%; Cd - 70,07%; Си - 69,35%, расход сернбй кислоты - 2,85 т/т i Zn + РЪ.Over 280 irrigations, zinc extraction was 69.80%; Pb - 62.40%; Cd - 70.07%; C - 69.35%, consumption of sulfuric acid - 2.85 t / t i Zn + Pb.
Пример 3 (сульф1адна медна руда). 15 кг руды смешали с органическим веществом, вз тым в количестве 2,5% от веса руды, что составл ет 0,375 кг, и загрузили в перкол тор . Выщелачивание вели 0,05 н. раст- вором серной кислоты, приготовленным на смеси рудничной и талой вод в соотношении .1:0,95.Example 3 (sulphonyl copper ore). 15 kg of ore was mixed with organic matter, taken in an amount of 2.5% by weight of the ore, which is 0.375 kg, and loaded into a percolator. Leaching conducted 0.05 n. with a solution of sulfuric acid prepared on a mixture of mine and melt water in a ratio of .1: 0.95.
Концентраци меди в растворе постепенно снижалась, начина с 15 г/л. За 180 орошений было извлечено 70,3% меди. Расход серной кислоты составил 2,5 т/т Си.The copper concentration in the solution gradually decreased, starting from 15 g / l. Over 180 irrigations, 70.3% of copper was recovered. The consumption of sulfuric acid was 2.5 t / t Cu.
