Description
Кроме того, при флотационном разделении продукта сегрегационного обжига, содержащего медь в сульфидной форме, а не в виде свободного металла, процесс флотации идет более успешно,In addition, when flotation separation of the product of segregation roasting, containing copper in sulphide form, and not in the form of free metal, the flotation process is more successful,
Способ опробован в лабораторных и укрупненно-лабораторных услови х.The method was tested in laboratory and integrated laboratory conditions.
Пример, Переработке подвергают медьоодержасдае железистые кеки автоклавного выщелачивани халькопиритового концентрата. Окислительный обжиг кеков провод т при 850900°С , Огарок подвергают сегрегационному обжигу в трубчатой вращающей печи при температуре. 850°С в течение 60 мин с введением в шихту 1 хлористого натри , 1,5% каменного угл и 10% сульфата кальци от веса огарка. Продукт сегрегации охлаждают без доступа воздуха и провод т флотационное обогащение в услови х: рН пульпы 8-11, расход бутилового ксантогената кали 100 г/т, соснового масла - 50 г/т. Врем основной флотации 15 мин, контрольной флотации - 10 мин. Выход I и И концентратов 15 ,7 и 6,6% соответственно. Суммарное извлечение в них меди - 92%, серебра - 86%, золота - 93%. Первый концентрат без перечистки содержит 8-9 % меди, при его перечистке получают высококачественный концентрат, содержащий 43% меди, 13% серы, 11% железа, 1381 г/т серебра и 90 г/т золота. Извлечение в него меди - 80% от количества в исходном кеке, а выход 2,3% от веса кека.For example, copper ore ferrous cakes from the autoclave leaching of chalcopyrite concentrate are processed. The oxidative calcination of cakes is carried out at 850900 ° C. The calcine is subjected to segregation roasting in a tubular rotary kiln at a temperature. 850 ° C for 60 minutes with the introduction of 1 sodium chloride, 1.5% bituminous coal and 10% calcium sulfate by weight of calcine into the mixture. The segregation product is cooled without air access and the flotation enrichment is carried out under the following conditions: pulp pH is 8-11, potassium butyl xanthate consumption is 100 g / t, and pine oil is 50 g / t. The main flotation time is 15 minutes, the control flotation time is 10 minutes. Output I and And concentrates 15, 7 and 6.6%, respectively. The total extraction of copper in them - 92%, silver - 86%, gold - 93%. The first concentrate without purification contains 8–9% copper, and when it is cleaned, a high-quality concentrate is obtained containing 43% copper, 13% sulfur, 11% iron, 1381 g / t silver and 90 g / t gold. Extraction of copper in it - 80% of the amount in the original cake, and the yield of 2.3% by weight of the cake.
