The main purpose of scheelite leaching process is to try to reduce the activity of calcium ions or WO42- in the aqueous phase, so that calcium tungstate gradually migrates to the dissolution direction. There are two main types of applicable scheelite leaching processes: one is to convert calcium ions in scheelite into calcium salts with lower solubility and enter the solid phase, and convert WO42- into soluble tungstates and enter the liquid phase; the other is to convert calcium ions in calcium tungstate into soluble calcium salts and enter the liquid phase, and convert WO42- into tungstic acid with lower solubility and enter the solid phase. Common leaching processes include alkaline leaching and acid leaching. Let's learn about them together!

The Shandong 1 million TPA zircon-titanium ore dressing project (Phase I) designed and constructed by Xinhai Mining Equipment has officially been put into operation. The dressing plant adopts Xinhai Mining Equipment's innovative customized technical solutions to achieve the "dry squeeze" of the original ore, accurately recovering 15 kinds of useful minerals! This project breaks through the limitations of the old domestic dressing methods and builds the first large-scale, automated, zero-emission zircon-titanium dressing plant in China. The mineral recovery rate and the comprehensive benefits of the dressing plant have been greatly improved, truly realizing the use of technology to improve quality and innovation to promote development!

On the premise that the volume and price of fluorspar are rising throughout the year, the development of fluorspar mines in 2024 is the key focus of mining companies. As a common non-metallic resource, fluorite is not only used in metallurgy, building materials, ceramics, glass and other industries. Following the development of science and technology, fluorite is also gradually used in various industries such as atomic energy, aerospace and aviation, and medical care. Its application scope is becoming more and more widely. Let’s take a look at Xinhai’s fluorspar ore beneficiation project completed in 2023!
