How to separate Fluorite from common gangue minerals

Fluorite is one of the common non-metallic minerals, also known as fluorite. Its chemical formula is CaF2. It is rich in color. It is an important fluorine-containing mineral in nature and the main source of fluorine for industrial use. Fluorite often coexists with calcite, dolomite, quartz, barite, pyrite, galena, sphalerite and other minerals, and is…

Application of lime in rotary kiln sintering

Basically, the content of Cao in sinter is about 11%, which is second only to iron, and Cao is mostly introduced by adding lime, so lime is of great significance for the production of rotary kiln sinter. Adding Cao containing materials to sinter proportioning can reduce the amount of limestone in blast furnace proportioning. If…

Elementary Knowledge of Flotation (4)

In the fourth chapter, Fodamon engineers continue to explain the basic knowledge of flotation. What is flotation speed? Flotation time? What is the relationship between flotation time and separation index? The so-called flotation speed refers to the recovery rate of useful components obtained by a certain ore in a certain flotation time and under certain…

Elementary Knowledge of Flotation (3)

In this chapter, Fodamon engineers continue to describe the knowledge of flotation. What is flotation speed? Flotation time? What is the relationship between flotation time and separation index? The so-called flotation speed refers to the recovery rate of useful components obtained by a certain ore in a certain flotation time and under certain operating conditions….

Elementary Knowledge of Flotation (2)

Today, Fodamon engineers continue to describe the knowledge of flotation in this chapters. What is preferential flotation? Mixed flotation? Partial mixed flotation and other floatable processes? In the flotation of polymetallic ores containing two or more useful components, the main problem is to solve the sequence of recovering various useful minerals. If one mineral is…

Elementary Knowledge of Flotation (1)

Based on years of beneficiation experience, Fodamon engineers will describe the knowledge of flotation in four chapters. What is floating beneficiation (flotation)? What is its scope of application? Flotation, namely foam flotation, is a mineral processing method for separating minerals according to their physical and chemical properties. In the process of flotation, the ups and…

Production Process of High Purity Quartz Sand

High purity quartz sand is a kind of stone made of natural crystal stone, silica and quartzite through careful selection and fine processing. It can be used to make all kinds of glass, as water treatment filter material, or as embryo and shaft material of ceramics and refractory porcelain. After years of experience, Fodamon engineers…

How to comprehensively recover metal vanadium?

How to comprehensively recover metal vanadium? The following is a brief introduction by Fodamon engineer, hoping to be helpful to you. (1) Recovery from vanadium slag Vanadium slag is a raw material for vanadium extraction with high vanadium content, and the recovery technology is relatively mature. At present, the general process is sodium roasting process,…

What is the difference between washed kaolin and calcined kaolin?

Kaolin is an inorganic non-metallic mixture. Calcining kaolin is to sinter kaolin in the calciner to a certain temperature and time, so as to change its physical and chemical properties to meet certain requirements. Water washed kaolin is the best raw material for producing high-grade porcelain. After deep processing and modification, the product can become…

Types of refractory gold deposits

With the large-scale mining of gold, the easily leachable gold resources are gradually exhausted, and the refractory gold will become the main resource of gold industry in the future. According to statistics, about 1 / 3 of the world’s total gold output is produced from refractory gold mines. Among the proven gold reserves in China,…
