Abstract

Procedeul de prelucrare a concentratelor de pirite aurifere, conform inventiei, prin topire în suspensie cu fondanti de zgurificare, rezultând o mata feroasa ce colecteaza metalele mobile de cupru în proportie de 95...98% si care fie ca se preamesteca cu alte mate pentru convertizare si obtinerea cuprului brut, fie ca se raceste lent si se macina la finetea necesara, pentru extragerea metalelor nobile prin cianurare, în scopul obtinerii unor randamente ridicate de recuperare a cuprului si respectiv metalelor nobile, efectueaza topirea în suspensie a concentratelor de pirita aurifera fara amestecarea prealabila cu alte concentrate de metale neferoase si eventuala racire cu 30...35 degree C/h la 800 degree C a matei evacuate din cuptorul de topire în suspensie, urmata de racirea cu apa si de macinarea la finetea de 0,074 mm în proportie de 92...95% în vederea cianurarii.The process of processing the golden pirite concentrate according to the invention by melting in suspension with zigzags, resulting in a ferrous matte which collects the mobile copper metals in a proportion of 95 ... 98% and which either is pre-mixed with other matrix for converting and obtaining raw copper, either slowly cooling and grinding to the required fineness, for the extraction of noble metals by cyanation, in order to obtain high copper and noble metal recovery yields, suspends the golden pyrite concentrates without pre-mixing with other non-ferrous metal concentrates and possibly cooling with 30-35 ° C / h at 800 ° C of the matte exhausted from the melting furnace in suspension, followed by water cooling and crushing to a fineness of 0.074 mm in proportion 92 ... 95% for cyanide.
