I'm looking for flux NaCl and KCl either seperatly or mixed for Al recycling industry. The material should be packed in big bags and must be kept dry. It's also a substance added to a furnace to help remove impurities. Impurities from metal as its being melted to form something else. The quantity is 20,000 to 30, 000 tons. Only serious manufactories/factories please. We will visit the plant before an order. No trading company please. I don't want to bargain. Let me know your best price, terms of payment.
