Build a sedimentation tank at the construction site, first discharge the sewage into the sedimentation tank, remove suspended matter and oil substances and neutralize them, and then discharge them into the river after testing to meet the discharge standards. During the drilling and pouring process, a screen is used to separate small gravel, sand and other solid particles in the mud, and the mud is discharged to the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank for full sedimentation. During the construction process, the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank are cleaned in time by an excavator, and the cleaned sediment is transported to the evaporation tank, and after natural dehydration and solidification, it is transported to the storage yard or the waste dump. For the abandoned mud water, flocculants are added to the mud water. Since mud water is a suspended liquid containing a certain am...

The ore drum screen is generally composed of a drum, a frame, a funnel, a reducer and an electric motor. In addition, different placement schemes can be designed for the equipment based on the production needs of the customer. When the mining drum screen is working, the crushed ore enters the drum from the feeding end. On the one hand, it will be affected by the centrifugal force generated by the rotation of the drum, and on the other hand, it will be affected by the jigging effect. The ore with a relatively large particle size will flow forward along the inclination of the drum. The ore with a suitable particle size will be screened out in turn according to the specifications when passing through the screen and fall into their respective funnels, and finally sent to the finished product pile by the belt conveyor.

Detailed explanation of iron removal methods in bauxite 1. Physical method The physical method is to remove iron from bauxite by using the difference in physical properties. Common physical methods include gravity separation, magnetic separation and flotation. 1. Gravity separation: Utilize the difference in density of different minerals to carry out mineral separation through equipment such as shaking tables and chutes. The density of iron minerals in bauxite is relatively large, and some iron minerals can be removed by gravity separation. 2. Magnetic separation: Utilize the strong magnetic characteristics of iron minerals, and magnetic separation can effectively remove iron minerals. Magnetite is common in bauxite, and magnetic separation can be used to separate them from bauxite. 3. Flotation: Utilize the difference in surface properties of different minerals, adjust the surface properties through flotation agents, and separate bauxite from iron minerals. In the flotation process, ...

 Drum screen: efficient separation of sand and gold Drum screen is one of the commonly used equipment in the process of gold panning, mainly used for the preliminary separation of sand and gold. Its working principle is to screen sand and gold particles through the rotation of the drum. The design of the drum screen usually includes multiple layers of screens, and screens with different apertures can separate particles of different sizes. This equipment is suitable for placer ore with high gold content, and can quickly remove large pieces of sand and gravel, leaving fine sand with high gold content. The advantages of the drum screen are simple operation and convenient maintenance, which is suitable for small and medium-sized gold panning operations.

The fully automatic river channel special sand screening machine is applicable to sand and stone separation, coarse and fine separation, sea sand and shell impurity screening, etc. Simple installation foundation: Because the entire equipment is a box-shaped frame structure, only a flat ground is required. Desalination and flushing method: Before flushing, the sea sand needs to be soaked in the fresh water soaking pool for no less than 24 hours, and then sent to the feed chute bucket by a loader. There are fresh water inlets on both sides of the chute bucket. Mechanical vibration is assisted by manual work to make the sea sand enter the cleaning drum under the continuous impact of fresh water flushing. The rotating stirring drum fully stirs and cleans the sea sand. The desalinated sea sand enters the grab bucket under the push of the built-in spiral blades of the drum, and is sieved through the discharge hopper and the discharge belt conveyor to screen out larger particles of impuritie...

Generally, wet weak magnetic separation is used to select titanium magnetite first, and then fatty acid collectors are used to float calcite. After the middlings are de-doped, ilmenite is floated. The beneficiation process of ilmenite depends on the nature of the material. Since the specific gravity of titanium minerals is relatively large compared to non-metallic gangue minerals, gravity separation can be used for pretreatment or rough separation and tailing; magnetic separation is widely used in iron removal operations to improve the concentrate grade of ilmenite, and can also be used to enrich ilmenite with a smaller specific gravity of gangue minerals; electrostatic separation is mostly used for purification operations when various non-conductive minerals are contained in titanium concentrate selected by other processes; flotation is more suitable for the beneficiation of primary ilmenite fine-grained ore. Placer-type ilmenite, especially sea sand-type ilmenite weathered from pegm...

The collected ore needs to be transported from the mining area to the beneficiation plant for preliminary purification. This process usually uses equipment such as trucks and belt conveyors. The ore needs to be crushed and screened during transportation to break the ore into smaller particles and remove waste rock and impurities. The ore particles after preliminary purification are easier to enter the subsequent beneficiation process, thereby improvin...

The tin ore beneficiation process is roughly divided into four links: crushing, pre-selection, flotation, and re-selection. The connection between each stage is appropriate. Only when the equipment configuration is reasonable, the whole process of tin ore beneficiation technology will be smoother and more convenient to operate. 1. Crushing and screening The nature of the tin ore is relatively simple, and a simple one-step crushing with a jaw crusher can achieve good results. The ore is crushed to 20mm, and then screened into two particle sizes of 20-4mm and 4-0mm. After crushing, the tin ore particles are uniform in size, beautiful in shape, and without over-crushing, providing high-quality raw materials for the next link, reducing the load of the grinding equipment, and having a good promoting effect on improving the grade of tin concentrate. 2. Pre-selection The 20-4mm ore enters the heavy medium cyclone for pre-selection, and then after a rod mill, the jig is used for pre-selection...
