Abstract

26,280. Marks, G. C., [Delprat, G. D.]. Nov. 28. Lead, silver, and zinc sulphides are extracted from ores by adding the powdered ore to a bath containing sodium, potassium, or zinc nitrate and dilute nitric acid and having a specific gravity of about 1À4. The sulphides float, and are removed by skimming &c.
