The invention relates to a non-pressure carbon sampler for an activated carbon sample in a leaching and adsorption pulp tank, belonging to the field of mineral processing. The non-pressure carbon sampler comprises an operation rod, wherein the two ends of an operation rope are respectively connected with the lower end of an operation handle and a prolonged end on a netted cylindrical shell wall; a netted arc lower cover is fixedly connected with the bottom of a guide rail; a netted arc upper cover covers the upper part of the netted arc lower cover and is fixedly connected with the guide rail; the upper end of a spring is connected with the prolonged end of the netted cylindrical shell wall; the lower end of the spring is connected with the netted arc upper cover; the netted cylindrical shell wall is in sliding connection with the guide rail; the netted cylindrical shell wall, the netted arc upper cover and the netted arc lower cover form a closed cylinder. The non-pressure carbon sampler is suitable for collecting the activated carbon samples on different deep parts in the leaching and adsorption pulp tank; the non-pressure netted structure has small interference on the activated carbon in the pulp fluid; under the coordination of the netted cylindrical shell wall, the netted arc upper cover and the netted arc lower cover, a certain volume of activated carbon in the pulp can be quickly collected without interference and the separation of the pulp and the activated carbon can be completed.
Description
technical field [0001] The invention belongs to the field of mineral processing, and in particular relates to a pressureless carbon extractor for immersing activated carbon samples in a slurry tank and a use method thereof. Background technique [0002] Activated carbon has been used in the gold extraction process for more than 100 years. In the cyanidation leaching gold extraction process, activated carbon is used to selectively adsorb gold and silver, so that the recovery of gold and silver in the carbon slurry method and carbon leaching method The rate has increased significantly. The density of activated carbon is the weight of activated carbon in the unit pulp. The appropriate carbon density and the reasonable stepped carbon density of each leaching tank are related to the grade of the gold-loaded carbon in the first tank and the gold grade in the tailing liquid, which affects the leaching and adsorption indicators. It is related to the economic benefits of the dressin...
