METHOD FOR IMPROVING THE DISSOLUTION OF GOLD IN WATER AND AQUEOUS GOLD-QUARTZ CONCENTRATE PRODUCED BY THIS METHOD Russian patent published in 2021 - IPC B22F9/02 B01J13/00 C01G7/00 C01B33/141 B82Y40/00 

FIELD: chemical processes.

SUBSTANCE: group of inventions relates to a method for producing a concentrate of an aqueous colloidal gold-quartz solution and to a concentrate of an aqueous colloidal gold-quartz solution exhibiting antimicrobial and antitoxic effects, usable in the perfumery, food industry, medicine, agriculture, veterinary medicine, biology, and other fields. To produce a concentrate, 50 g of washed river quartz sand is added to 1 liter of disciplined water, the resulting mixture is placed in an ultrasonic bath at a power of 35 W and subjected to ultrasonic impact for at least 20 minutes. The resulting colloidal aqueous quartz solution is separated from the residual quartz sand crystals, and 0.3 g of food grade gold leaf is added thereto, the resulting mixture is placed in an ultrasonic bath and subjected to impact of shock ultrasonic waves at a frequency of 18 to 44 kHz while heating to 40°C for at least 30 minutes until a concentrate of an aqueous colloidal gold-quartz solution of golden colour is produced. The concentrate of an aqueous colloidal gold-quartz solution comprises, mg/l: silicon 20 to 40, gold 0.05, disciplined water the rest.

EFFECT: concentration of colloidal gold particles in water when producing a colloidal system is increased.
