It is generally believed that only when the rock ore and placer reach the following content can they have industrial mining value. Fodamon engineers summarize as follows. The content of TiO2 in ilmenite is between 10% – 40%, or the content of TiO2 in rutile is more than 3%; the content of ilmenite in placer…

Construction waste is construction waste caused by house demolition and rebuilding of urban roads. The main materials are massive piles of concrete, waste bricks, waste tiles, glass, etc., which not only occupy a lot of land resources, but also seriously affect the decline of urban environmental quality. Fodamon engineers made the following summary based on…

It’s also crushing stone. What are the differences between Impact crusher and Hammer crusher. Let’s take a look at some of the conclusions given by Fodamon’s engineers. Different crushing chamberThe crushing chamber of impact breaking is large, and the feed port is low and large. The crushing of materials not only depends on the impact…

The separation of copper and arsenic is mainly to solve the separation problem of copper minerals and arsenopyrite, which can be summarized as follows: (1) Highly selective collector. It is very important to enlarge the separation of the two minerals by using selective collectors. For example, the combination of xanthate and black medicine of butylammonium,…

Most of the useful minerals and gangue minerals are closely combined. Therefore, before high-efficiency separation, it is necessary to solve the problem of dissociation of the target minerals and gangue minerals. After the minerals reach monomer dissociation, qualified products can be obtained through separation operation. At present, grinding classification is a common and effective way…

“The world fluorite is in China, China fluorite is in Zhejiang, Zhejiang fluorite is in Jinhua, Jinhua fluorite is in Wuyi. ” For a long time, this has become the consensus of the fluorite industry. China is rich in fluorite resources. Fluorite deposits in Zhejiang Province are mainly distributed in Suichang, Wuyi and Changshan areas….

High purity quartz sand is a kind of quartz sand with SiO 2 content higher than 99.9%, which is white powder with no discoloration and low impurity content. High purity quartz sand has high temperature resistance, excellent chemical properties, excellent electrical insulation and transparency, etc. It is an irreplaceable mineral raw material for high-tech industry….

Fodamon engineer has accumulated many years’experience in sand and stone crushing and sand making industry, and summarized the following knowledge about sand making for your reference. What are the main advantages of dry process? The main advantages of dry process are as follows:a, The moisture content of manufactured sand is low, generally less than 2%….

The floatability of copper oxide ores is generally worse than that of copper sulfide ores, and is greatly influenced by the existing form of copper in minerals and gangue composition. For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica…
