Sulfides of industrial significance are antimony trisulfide and antimony pentasulfide. The physical and chemical properties of barium sulfide are listed in the table below. Table Physical and chemical properties of barium sulfide species Physical properties Chemical properties Disulfide Sb 2

B and other magnetic poles These magnetic potential equations represent a set of equipotential surfaces of a magnetic pole and may also be referred to as equipotential surface equations. The shape of the magnetic pole we need can be selected from the set of equipotential surfaces represented by

Construction machinery with high strength bolts for corrosion is generally plated surfaces of zinc or bluing treatment, disadvantage of this process is that the difference between the corrosion resistance of the bolt surface, rust, galvanized bolts and further care in hydrogen embrittlement. For t

(1) Combustion reaction and its thermodynamic analysis The fixed carbon content of the fuel for sintering is generally 68-80%, and it can be burned when the temperature rises above 700 °C. When sintering is ignited, the ignition temperature should be between 1100 and 1200 ° C because the surf

   These collectors are characterized by a hydrophilic group usually composed of divalent sulfur atoms inside the molecule, while the hydrophobic group has a small molecular weight and has a trapping effect on sulfide minerals, but has no trapping effect on gangue minerals such as quartz and

Its structure is basically the same as that of a common hydrocyclone. The original medium used is a resuspension, and now there is also a medium for water. The heavy medium cyclone has a single cone and a double cone; the upper part of the single cone is cylindrical and the lower part is conical; t

Partially mixed flotation process The process of first extracting two useful minerals from the ore to obtain a roll concentrate, and then separating the mixed concentrate into a single concentrate, is called a partial mixing flotation process (Figure 7). This is the most widely used process in pr

Xanthate readily generated with various alkylating agent effect thioester, xanthate mainly molecule is a hydrocarbyl substituted alkali metal generating xanthate esters of the general formula ROCSSR', which can be seen as xanthate Derivatives. These collectors are non-ionic polar collectors, wh

Xuzhou double-armed factory crusher (hereinafter referred to as double-machine) produced a unique spin fine sieve structure design, set crushing, screening in one, using an edge drive to drive rotary screen cylinder, the bearing away from the crushing chamber can be at an elevated temperature Work

I. Introduction Domestic large and medium-sized open pit mines are basically drilled with a roller rig , and their maximum penetration depth can reach 25.0 m. If it is calculated by the conventional ultra-deep 2.0~2.5 m, the maximum section height of the blasting should be 22.5~23.0 m, which is 1~

40 years Germany has been producing iron ore lepidolite from a tungsten-tin ore with magnetic separation and flotation. The mine only recovered tungsten and tin minerals in the 1920s, while iron-lithium mica was abandoned as tailings. Due to the market demand, the iron-lithium mica concentrate was

(I) Beneficiation processing method 1. Beneficiation method of mineral processing bentonite is generally divided into dry method and wet method. Most of China's current mines use dry process beneficiation. Dry beneficiation is generally used to treat bentonite with better ore quality. The meth
