Process for the continuous recovery of gold and other metals from sea water

摘要

A quantity of Gilsonite Asphalt in proportion ranging from one-tenth gram to three grams per gallon of water to be treated is added in finely powdered form to sea water to coagulate plankton containing metals in the water in a coated treating tank. Treated water is then filtered with a microfine electric filter to remove the plankton and gold and other metals from the sea water. The precipitate is dried and then redissolved in a suitable reagent. Gold and other minerals are separated electrolytically. The treated water then can be desalinized in known manner such as by solar distillation.
