Title:
A manufacturing method of the exudation generation liquid containing platinoid elements
Document Type and Number:
Japanese Patent JP6264566
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method where impurities are removed from a solution or a precipitate containing platinum group elements and containing an oil content or tin, thus a solution suitable for refining suitable for the refining of the platinum group is obtained.SOLUTION: Provided is a method for producing a leach product solution including platinum group elements suitable for the separation of platinum group elements from an oil or tin-containing platinum-containing matter, in which the oil or tin-containing platinum element-containing matter is roasted at 500 to 800°C to form incineration ash, and the incineration ash is mixed with hydrochloric acid and an oxidizer at 80 to 95°C to produce a platinum group element-containing leach production solution suitable for the separation of platinum group elements.
