What are the common beneficiation methods for nickel ore?

Nickel is an indispensable metal element in the world. It is a necessary raw material for military manufacturing, machinery manufacturing, atomic energy industry, ultrasonic industry and communications. The chemical symbol of nickel is Ni, with an atomic weight of 58.69. It is iron-friendly, and its content is second only to silicon, oxygen, iron, and magnesium, ranking fifth. There are many types of nickel ore. According to the mineral properties, they are mainly divided into copper sulfide nickel ore and copper oxide nickel ore. Among them, copper is the main impurity mineral in nickel ore, followed by lead, zinc, arsenic, fluorine, manganese, antimony, and bismuth. , Chrome, etc. In the process of beneficiation, copper-nickel sulfide ore beneficiation and copper-nickel oxide ore beneficiation are also the main focus. Let us briefly introduce these two types of beneficiation methods! 1. Beneficiation method of copper-nickel sulfide ore 2. Beneficiation method of nickel oxide ore

How to treat the mud wastewater after washing the stone powder in the quarry

Recycling of reclaimed water is an important rear guarantee for the normal mining of the sandfield project. The processing system must be foolproof in the sandfield mining project and reach 100% reliability. The reliability of this processing system is mainly reflected in several aspects: 　　(1). The reliability of the overall design, that is, the timeliness of slag treatment and the adaptability to the slurry quality; 　　(2), configuration with rich processing capabilities. Including the backup function of the whole equipment and assembled equipment. 　　 (3), the reliability of the performance, quality, and life of the equipment itself; 　　(4), through the piping system and valve group to switch each group of equipment, mutual standby.

What are the differences between open-circuit grinding and closed-circuit grinding of ball mills, and how to choose them in the concentrator?

In the concentrator, the grinding stage is an important part of the investment of a large amount of capital and energy consumption. The grinding process controls the particle size change of the entire beneficiation process, and has a greater impact on the productivity and recovery rate of the concentrator. Therefore, the ball mill is in a certain grinding How to reduce costs and increase productivity on fineness standards is a matter of great concern. There are two types of grinding methods: open-circuit grinding and closed-circuit grinding. What are the characteristics of these two grinding methods? Which kind of grinding method can be selected to realize the efficient use of grinding equipment and increase productivity? Methods and characteristics of open-circuit grinding and closed-circuit grinding Open-circuit grinding: refers to the grinding operation, after the material is fed into the ball mill and discharged after one grinding, it directly enters the next mill or the next process. The advantages of open-circuit grinding: the production process is relatively simple, and the investment cost is lower. And its disadvantage is that it has lower production efficiency and produces larger energy consumption during production.

To improve the screening efficiency of the linear vibrating screen, these aspects cannot be ignored!

The linear vibrating screen is one of the main equipment in the crushing and screening process, and it is also the key equipment to provide qualified materials for subsequent operations. Its screening efficiency directly affects the subsequent operations. In the actual plant, the main factors that affect the screening efficiency of the linear vibrating screen include: the nature of the material, the parameters of the screen surface structure, and the vibration characteristic parameters. Below, we will specifically analyze how the above aspects affect the screening effect of the linear vibrating screen. Low friction coefficient and superior thermal conductivity. It is mainly used for processing aluminum alloys, copper alloys and other non-ferrous metals, woodworking materials, and hard non-metallic materials.

The main process flow for the production of washed kaolin

Kaolin is a non-metallic mineral, clay and clay rock mainly composed of kaolin clay minerals. Because it is white and slender, it is also called white cloud soil. Named after Gaoling Village, Jingde Town, Jiangxi Province. Its pure kaolin is white and slender, in the shape of soft soil, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, halloysite, mica, illite, montmorillonite, quartz, feldspar and other minerals. Kaolin has a wide range of uses, mainly used in papermaking, ceramics and refractory materials, followed by raw materials for coatings, rubber fillers, enamel glaze and white cement, and a small amount in plastics, grinding wheels, soap, pesticides, medicine, chemicals, building materials, national defense, etc. Industrial sector

Installation instructions and methods of spiral chute

1. First, check the quality of the glass fiber reinforced plastic spiral sheet (especially the quality of the working surface). Only when the size and shape meet the requirements can be assembled. 2. The fastening bolt hole of the spiral piece is generally prepared by the manufacturer in advance. If the manufacturer does not process, in order to ensure compatibility, the same template must be used to make holes. 3. Connect the five spirals to form a set of spiral chute with bolts, and place them horizontally. The connection of two adjacent flanges is based on the smooth transition of the inner surface. When connecting, pay special attention to the surface of the bottom piece not to be lower than the surface of the corresponding bottom piece. Along the radial direction. Take the position from the outer edge (in the direction of the groove width) as the reference, and it is not allowed to be further inward than the outer edge of the lower piece, in order to prevent the scattering of the ore flow. If there is a gap in the connection part, it needs to be smoothed with putty. 4. Combine the four-head (or two-head or three-head) spiral chute in a group of five connected into one, and distribute them into the desired shape. 5. Install 4 (3) pillars on the 4 (or 3, 2) spiral chutes in turn, fix the spiral chute and pillars with bolts, cross) the tripod), so that the spirals of each head are evenly distributed around the circumference. Finally tighten all bolts, after installation 6. When the cutting groove of the mining tank and the product is set at the beginning and end of the spiral chute, the connection part must not leak water. When there is a gap, it must be tightly sealed with paint to ensure that the groove surface is too smooth. 7. The ore homogenizer and the product integrated bucket are not connected to the fuel tank bracket, and are freely placed on the bracket. When installing, pay attention to the correct position as shown in the figure. Each row of the distributor must be matched with the corresponding feeding trough. 8. The foundation of the spiral chute generally does not need to be fixed, but after it is placed on four (three) planes at the same level, after installation, in order to check whether the longitudinal axis of the spiral chute is vertical, shims can be placed under the pillar to adjust Plumbness. The spiral slideway must be set up at an appropriate height, and the spiral slideway pillar and base must be properly connected.
