Beneficiation process includes ore washing, crushing and beneficiation. In the process of enriching valuable metals from ores with low content and multi metal symbiosis and processing them into concentrates with high metal content, various types of beneficiation agents need to be added. Beneficiation reagents mainly refer to collectors, frothers, inhibitors, flocculants, modifiers, extractants, matrix improvers and diluents used in hydrometallurgy, etc., involving hundreds of inorganic or organic compounds. Our company produces mineral processing reagents such as xanthate series, dithiophosphate series, thiocarbamates, sodium thioglycollate, copper sulfate, etc.
