Abstract
Tetraedritový koncentrát v zmesi ao šideritovým koncentrátom v poměre 1 j 1 až 17 s 1 ea praží pri teplote 500 až 800 °C a době praženia 2 až 8 bodin, pričom sa získá měděný výpražok s nízkým obsahom antimčnu.Tetrahedrite concentrate in a mixture with siderite concentrate in a ratio of 1 j 1 to 17 with 1 ea is roasted at a temperature of 500 to 800 °C and a roasting time of 2 to 8 points, whereby a copper powder with a low antimony content is obtained.
Description
Vynález sa týká spĚsobu spracovania tetraedritováho koncentrátu s obsahom ortuti, médi, antimónu, bizmutu, striebra v zmesi so sideritovým koncentrátom pražením, pri ktorom sa ziska měděný výpražok a pražné plyny obsahujúce antimón a ortuf. V 8Účasnosti sa tetraedritové koncentráty obsahujúce ako hlavné úžitkové složky ortyfi, meó, antimón, bizmut, striebro spracúvajú technológiou oxidačného praženia, pričom sa zlskava měděný výpražok a pražné plyny obsahujúce ortuf. Měděný výpražok obsahuje 15 - 25 % médi a 4 - 12 % antimónu. Uvedená zloženie měděného výpražku Je nevyhovujíce na óalšie spracovanie pre medenú hutu pre vysoký obsah antimónu, preto sa v súčasnej praxi pře zníženie obsahu antimónu v medenom výpražku používá chloridačné praženie ako óalší stupeň praženia za pridávania chloridne amónneho pri teplote cca 850 °C, Základným nedostatkom súčasného stavu je to, že vzniká měděný výpražok s vysokým obsahom antimónu.BACKGROUND OF THE INVENTION The present invention relates to a process for the treatment of tetrahedrite concentrate containing mercury, medium, antimony, bismuth, silver in a mixture with a siderite concentrate by roasting, in which copper melt and antimony-containing and gaseous gases are obtained. In the present case, tetrahedrite concentrates containing as major orthphi, meo, antimony, bismuth, silver useful components are processed by oxidative roasting technology, with copper sputtering and orthofetter gases being obtained. Copper baking contains 15-25% medium and 4-12% antimony. Said composition of copper spraying It is unsatisfactory for further processing for a high-antimony copper smelter, therefore, in the current practice, to reduce the antimony content of the copper spraying, chlorination roasting is used as an additional degree of roasting with addition of ammonium chloride at about 850 ° C. the condition is that a high antimony content of copper is produced.
Uvedený nedostatok súčasného stavu rieši vynález, ktorého podstata spočívá v tom, že sa tetraedritový koncentrát v zmesi so sideritovým koncentrátom v poměre 1 : 1 až 7 : 1 praží pri teplote 500 - 800 °C a získá sa měděný výpražok s nízkým obsahom antimónu v jednom technologickom uzle, pražné plyny obsahujúce antimón a ortuf sa vedú cez odprašovací cyklón a filter do kondenzácie. Týmto sposobom sa v jednom technologickom uzle ziska měděný výpražok, ortuf a antimónový koncentrát. PřikladSUMMARY OF THE INVENTION The present invention is solved by the present invention, whereby the tetraedrite concentrate in a mixture with siderite concentrate in a ratio of 1: 1 to 7: 1 is roasted at 500-800 ° C to produce a low antimony low copper copper yield. the technological node, the antimony-containing roast gases and the mercury are passed through a dedusting cyclone and a filter into condensation. In this way, in one technological node, copper baking, ortuf and antimony concentrate is obtained. Example
Tetraedritový koncentrát β obsahom 17,55 % Cu a 6,35 % Sb v zmesi so siderito vým koncentrátom o obsahu 35,20 % Fe a 6,7 % Si02 Je pražený v pomere 3 : 1 pri teplote 720 °C a době praženia 4 hodiny,Tetraedrite concentrate β containing 17,55% Cu and 6,35% Sb mixed with siderite concentrate containing 35,20% Fe and 6,7% SiO2 Roasted 3: 1 at 720 ° C and roasting time 4 clock,
Ziska sa výpražok s obsahom 16,87 % Cu a 0,87 % Sb.A precipitate containing 16.87% Cu and 0.87% Sb was obtained.
