METHOD FOR REMOVING FREE GOLD FROM SCALES AND ORES AND A DEVICE FOR ITS IMPLEMENTATION (OPTIONS)

摘要

1. The method of extracting free gold from placers and ores, according to which, a) prepare a gold-bearing pulp, b) use an absorbent prepared on the basis of liquid hydrocarbons, while the density of the absorbent is lower than the density of the mentioned pulp, c) provide contact of the pulp with the absorbent, wherein free gold is transferred from the pulp to the absorbent, d) free gold is separated from the absorbent by filtering the absorbent, characterized in that e) volumetric contact of the pulp with the absorbent by filtering the pulp Erez, at least one absorbent layer, f) wherein the absorbent is used having the oxidation potential (Eh) and characterized by an adhesion to the free gold least 40 Pa.2. The method according to claim 1, characterized in that the volumetric contact of the pulp with the absorbent is carried out by filtering the pulp from top to bottom through at least one layer of absorbent material. A method according to any one of claims 1 or 2, characterized in that the absorbent has an oxidizing potential (Eh) of at least +1400 mV. 4. A method according to any one of claims 1 or 2, characterized in that liquid hydrocarbons are used as absorbent, for example: mineral oil obtained after processing fuel oil, engine mineral oil of various grades or mixtures thereof with the addition of activating substances and heat treatment of the mixture. A method according to any one of claims 1 or 2, characterized in that the density of the absorbent is 0.72-0.93 g / cm. A method according to any one of claims 1 or 2, characterized in that the pulp density is 1.1-1.6 g / cm. A method according to any one of claims 1 or 2, characterized in that the pulp is filtered through an absorbent layer under a pressure of not more than 0.1-0.5 m�
