Document Type and Number:
Japanese Patent JP2017088994
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pump capable of collecting gold efficiently at every point of labor, time and yield, from gold dust which cannot be collected completely, by pumping out gold dust and water simultaneously from a river, and by mixing mercury therewith.SOLUTION: While inputting mercury in the middle of pumping-up together with sand pumped up from a river by a screw-type pump, and while pumping up the mixture, water, mercury and gold dust are rubbed together, to thereby perform a pumping-up work and a mixing work simultaneously.
