Three replacement zinc powder replacement precipitators are required for continuous displacement precipitation.Zinc powder is obtained by the sublimation method to rapidly cool zinc vapor in a large-volume condenser. The particle size is less than 0.01 mm, which is easily oxidized, so it must be tightly sealed during transportation or storage. Carbon in pulp Carbon in Pulp (CIP) is a new process for recovering gold from activated carbon by cyanide leaching. In 1973, the world’s first industrialized CIP plant was put into operation at the Homest Gold Mine in the United States, and was quickly promoted to countries around the world. The carbon slurry method is mainly applicable to gold-containing oxidized ores with high sludge content.(1) Pretreatment: cyanide pulp should be sieved to remove coarse particulate materials (such as sand) and wood chips before adsorption, so as to avoid the influence of these impurities on the adsorption and separation of gold-loaded activated carbon and de-gold slurry, and also avoid the accelerated wear and removal of activated carbon. Gold activated carbon regeneration is difficult; activated carbon should also be pre-ground to remove sharp corners and edges before entering the adsorption tank. If not pre-ground, these debris will enter the de-gold slurry to cause gold loss.(2) Adsorption: Activated carbon is added to the fully leached pulp, and the activated carbon adsorbs gold in the cyanide slurry to become gold-loaded charcoal. The adsorption is carried out in an adsorption tank (carbon slurry tank). There are many types of adsorption tanks. For the treatment of
