Recovery of ionic type rare earth from kaolin concentrate
摘要
Abstract
Kaolin concentrate has the characteristics of fine grain size, high viscosity, higher permeability and poor performance of solid-liquid separation, and high aluminum content. Southern kaolin is often accompanied by rare earth. There is not a set of mature technology applied in the industrial production to solve how to extract qualified rare earth from kaolin concentrate at present. Based on the characteristics of rare earth in kaolin ore, researchers had explored a set of mature technology process and the completion of the production line to provide technical support for the recovery of ionic rare earth in kaolin concentrate by the laboratory test, expansion test and industrial test. Both the leaching liquid and kaolin concentrate were added to the pulp pool for stirring and leaching, to obtain the filter cake when the pulp was being filter pressed by plate and frame filter, which was the kaolin concentrate. The filtrate was the rare earth products when it was subsequently treated. At the same time, the production line had been completed, and had produced more than 10 tons of rare earth, which provided an effective technique for recovering ionic rare earth in kaolin concentrate.关键词
