Automatic control of beneficiation process
Introduction
Mining is a process used to extract useful minerals, metals, and other resources from earths crust. Machines and equipment have been used to improve the efficiency of the mining process since the early 20th century, and automation has become increasingly important in the industry ove......

seabed mining
Undersea mining is the process of retrieving minerals from the ocean floor. Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 meters below the ocean’s surface.
Deep-sea mining is a relatively new mineral retrieval......
Diatomite beneficiation
Silicate Mineral Beneficiation
Silicate ore beneficiation is the process of separating valuable minerals from unwanted material using a variety of physical and chemical processes. During this process, the ore must be crushed, ground, and then treated with a chemical solution. The solution used de......
Wieliczka Salt Mine
The Salar de Uyuni, also known as the Salar de Tunupa, is an immense salt flat located in southwestern Bolivia, near the crest of the Andes Mountains. The area spans more than 10,000 square kilometers (4,000 sq mi) and is thought to be the worlds largest salt flat. The Salar de Uyuni is home to th......
Chlorination Roasting
Chlorination roasting, also known as powder-chlorination roasting technique, is a process of heat treatment carried out on metal and metal alloy materials. The main purpose of this process is to increase the cracks-resistance and corrosion-resistance of the material and increase wear-resistance an......

, 关于Wegeners Continental Drift Theory
Wegener’s Continental Drift Theory, first proposed by German scientist Alfred Wegener in the early 20th century, proposed that the continents had once been joined together and had since moved apart, an idea that contradicted long-held popular beliefs. Wegene......
crustal abundance
The crust is the outermost layer of the solid Earth and composed of two major types of rocks: the oceanic crust and the continental crust. The abundance of crustal rocks varies with location and depth, but can be measured in parts per million (ppm) or billion (ppb). The continental crust contains ......
Physical and mechanical properties of rock mass
Introduction
Rocks as a natural material consist of numerous different minerals and they form the basis of the earth’s crust. In addition, their composition and texture determine their physical, mechanical and chemical characters. Therefore, rock mechanics deals with the interactions between roc......
Zirconium Smelter Design
The Design of a Zirconium Smelting Factory
Zirconium is a grayish-white metal, derived from the mineral zircon, with a wide range of uses. It has excellent corrosion resistance, very high melting point, and is used in nuclear reactors, metallurgy, electronics, chemical industry and other fields. ......
foundation
The foundation of the earth is composed of many layers, which include the core, mantle, and crust. The earths core is the central part of the system and is composed of two parts; the inner core and the outer core. The inner core is made up of solid iron and nickel and is a solid sphere. This layer ......
