Description
Известны процессы выделени благородных металлов н теллура из сульфатных растворов нри выщелачивании обожженных медеэлектролитных шламов путем обработки растворов медью, никелем или другими металлами. Описываемый способ в отличие от известных позвол ет раздельно выделить благородные металлы и теллуровый цементат, содержание теллура в котором известными приемами довод т до 80-85Vo.There are known processes for the recovery of precious metals n tellurium from sulphate solutions when leaching burned copper electrolyte slimes by treating the solutions with copper, nickel or other metals. The described method, in contrast to the known ones, makes it possible to separately distinguish noble metals and tellurium cements, the tellurium content of which is brought to 80-85Vo by known methods.
Предлагаемый способ выделени (цементации) благородных металлов и теллура из сульфатных растворов, получающихс при сернокислотном выщелачивании обожженных медеэлектролитных щламов, состоит в том, что шламы, содержащие платину, обжигают при температуре 600-650°, а щламы, содержащие золото и серебро, - при 550° и подвергают затем серно1 ислотному выщелачиванию; при этом в получаемый раствор переходит 85-90% теллура, основна масса меди и некоторое количество благородных металлов.The proposed method for separating (cementation) of noble metals and tellurium from sulphate solutions obtained by sulfuric acid leaching of calcined copper electrolyte slimes is that slimes containing platinum are burned at a temperature of 600-650 ° C, and slimes containing gold and silver are burned at 550 ° and then subjected to sulfuric acid leaching; at the same time 85-90% tellurium, the main mass of copper and a certain amount of noble metals pass into the resulting solution.
Подавл юща часть теллура при указаннвмг температурах обжига щлама в растворе получаетс в шестивалентной форме, поэтому теллур цементируетс только в гор чем растворе. С целью раздельного получени теллура и благородных металлов, раствор обрабатывают медным, никелевым или каким-либо другим металлическим порошком сначала при комнатной температуре, при которой нацело цементируютс только серебро, платина, золото и другие благородные металлы, & также осаждаетс больша часть селена. После отделени благородных металлов и части селена раствор нагревают до кипени и обрабатывают снова медью, никелем или другим металлом.. Затем содержание теллура в полученном теллуровом цементате известным способом довод т до 80-85%.The overwhelming part of tellurium at specified calcining temperatures of slime in solution is obtained in hexavalent form, therefore tellurium is cemented only in hot solution. In order to separate tellurium and noble metals, the solution is treated with copper, nickel or some other metal powder, first at room temperature, at which only silver, platinum, gold and other precious metals are fully cemented, & most of the selenium is also precipitated. After the separation of noble metals and part of selenium, the solution is heated to boiling and treated again with copper, nickel or another metal. Then the tellurium content in the tellurium cementate obtained in a known manner is adjusted to 80-85%.
