The neutralization method has the characteristics of simple system, reliable and low cost. Depending on the neutralizing agent selected, it is usually divided into lime, lime milk, neutralization method, limestone neutralization method and limestone-lime combination method. The limestone neutraliz

Tangdan low grade copper oxide ore, the mineral composition of complex embedded fine particle size, the oxidation rate and a high rate, a high gangue content of calcium, magnesium, copper is a typical refractory oxide. Since copper oxide ore Tangdan characterized as a "high oxidation rate, hig

1. Cold storage capacity: The size of the cold storage should be designed based on the maximum amount of agricultural products to be stored throughout the year. This capacity is calculated based on the volume required to store the product in the cold storage, plus the distance between the rows, t

1. Mineral processing of molybdenum ore and formation of molybdenum-selected sewage Generally, the selection of molybdenum minerals is carried out by a flotation method. In the process of molybdenum selection, flotation reagents are added. In addition to being partially consumed in the ore sorting

Common major oxidizing minerals are: Malachite CuCO 3 ·Cu(OH) 2 , containing 57.5% of Cu, has good floatability, can be directly floated by fatty acid or sodium hydroxyphosphate, or can be floated with high-grade xanthate after vulcanization with sodium sulfide. When vulcanized, ammonium sulfat

Our country is a national shortage of copper metal, according to the prediction of mineral resources and the current development rate, by 2020, will be a serious shortage of copper resources. Although China's copper metal reserves have more than 60 million tons, but rich in ore, rich in ore, lo

The Law of the People's Republic of China on Mineral Resources is a large law for the exploration, development and utilization of mineral resources in China. It is the legal basis for the state to lead, organize and manage the exploration, development and protection of mineral resources. The sta

advantage: (1) There are no moving parts, the structure is simple, easy to manufacture, and the cost is low; (2) The processing capacity per unit volume is large and the floor space is small; (3) The classification efficiency is high, and the classification efficiency of other classifiers is gen

The hydrocyclone is a widely used wet mechanical separation and classification equipment , which has many advantages such as simple structure, no moving parts, small floor space, large processing capacity, low equipment manufacturing and maintenance cost [1] . In recent years, with the rapid develo

First, the method of determining the speed of the mill In the grinding machine of the throwing work, the grinding action mainly comes from the kinetic energy of the steel ball reaching the falling point. The magnitude of this kinetic energy is related to the falling height (H) of the steel ball, a

Barite is an important mineral resource and plays an extremely important role in many industries and fields. The quality of barite ore is generally poor, and it needs to be sorted and purified to increase the content or specific gravity of barite. So what is the processing equipment for barite, and

General requirements for technical conditions for mining of wollastonite deposits The Single Girder Gantry Crane is mainly used outdoor working site for hoisting and moving of materials. It has the advantages of simple structure, convenient transportation and installation, light self-weight
