Process for processing pyrite ores containing precious metals.
EMI1.1
Subject to the presence of oxidizing agents in order to convert the iron sulfides into sulfates, which can then usually only be removed with extraordinary difficulty in later stages of the extraction process.
The invention now consists in an embodiment of this process and is characterized by the use of a certain temperature of approximately 4250 ° C. when roasting the iron, nickel, cobalt, etc.-containing ores, whereby all iron is converted into soluble. Form takes place in the first stage of the preparation process.
According to the present process, the ores are supplied with air or
