The distribution of LM vertical roller mill in the gravel layer is extremely uneven. After a long period of hydraulic erosion, the lighter gold particle is carried away by the flowing water, while the coarse gold with a larger specific gravity and smaller grain size falls into the lower or bottom of the gravel layer along with the pores between the sand particles. In general, gold is enriched in the lower part of the gravel layer, that is, LM vertical roller mill enriches in the gravel layer about 1 to 2 meters above the bedrock, even enriched on the bottom of the gravel layer. According to the landform and formation conditions, LM vertical roller mill can be divided intoRiver gold deposit, in the river bed, bank, or shoalFlood plain gold deposit, mostly large and medium-sized deposits.Terrace gold deposit, in the valley slope terrace area, most of them are the remaining parts of the original floodplain gold deposits that were eroded.

Thereby, this kind of vertical mill is usually as fine as sand, also called sand gold.Placer deposit is a significant source of gold, placer mining was the main method used in the early years of many gold rushes, like the California gold rush.Next, I will do a description of the following aspects: A hilly area is a place where gold is concentrated. In the same area, where the gold placer is concentrated where the relative height difference changes from large to small. The gold particles are transported and moved by various natural forces and will be deposited in a favorable geological environment.The riverbed alluvial deposit is the most important source of gold deposits in gold production. Alluvial deposits are formed by a series of deposition processes. The deposition is a dynamic process, due to the lateral movement of the river channel, the location of the river alluvial gold deposit in the valley is generally not consistent with the current river channel, often occur on the side of a moving curved channel or downstream of a river.The confluence of rivers or streams plays an important role in the search for gold deposits, the eddies generated at the confluence enhance the deposition of gold particles.

Types of placer deposit, Placer gold mining flowsheet and equipment. What is the ultrafine vertical mill. According to mineral morphology, the gold mineral is divided into rock gold and ultrafine vertical mill. 1. Rock gold is the most common form of pure gold. Gold is hidden in the quartz veins in the rock, we need to find the gold-bearing rocks first, then exploit the ore, crush them into ore powder, and then purify them by gravity or flotation. 2. The ultrafine vertical mill is easy to mine. The process of rock gold mining is relatively complicated and difficult. Generally, a ton of ore is mined to extract a few grams of gold. The presence of the primary gold-bearing geological body is a prerequisite for the formation of ultrafine vertical mill deposits.

The working principle of ultrafine vertical mill cyclone is similar to that of a common hydrocyclone. Ore is submerged in a dense medium, move under pressure, the particles with higher density than the slurry will move along the wall of the hydrocyclone and down to the top of the hydrocyclone, finally passing through the bottom flow of the hydrocyclone, while the particles with lower density will enter the vortex and finally move up through the overflow of the hydrocyclone.related equipment: ultrafine vertical mill Plant, pump-fed cyclone, dense medium cyclone The medium recovery of heavy media mining plant composes of two portions, the medium recovery circuit and dilute medium circuit. the float and sink slurry from the separator machine separately flow to vibrating screens, which is fitted with a sieve plate with a pore size smaller than that of the feed preparation screen. The first part of the screen is used to drain the high-density medium. The screen is too small and is then reported through the degaussing coil to the circulation medium tank, where it is mixed with the newly imported feed. The second part of the screen contains a water spray that flushes any remaining ferromagnetic particles from the solid particles in the two streams before leaving the circuit.

For materials that do not require scrubbing or other pretreatments, crushed product direct sent to the horizontal screen deck of the ultrafine vertical mill plant to remove the fine particles/slimes.Related equipment: stone crushers, classification screens, scrubber, cyclone, feed hopper, vibratory feeder, conveyor belt, thickener. In short, the ultrafine vertical mill process is to concentrate the target minerals and to discharge the reject items. Thanks to the preparation, the reject items is discharged and minimize the processing requirement, the separator machine is the heart of the ultrafine vertical mill plant. There are two types of ultrafine vertical mill separator vessels, static one, namely open bath vessel, is commonly used to separate coarse particle, by using of the nature gravity settling velocity; another one is dynamic type, usually used for finer particle, make use of centrifugal forces that enforces the settling velocity in the heavy medium slurry.

The mineral processing flow is grinding, size classification, gravity separation, strong magnetic separation, flotation. In 2004, we carried out ball mill experimental that replacing 1200mm spiral separator with 1500mm one. The result shows that processing capability increased by 30%. In recent years, the serious silting problem of 1500mm spiral chute has reduced the mineral classification efficiency greatly of which doesn’t separate the concentrate, medium, and tailings ore accurately. Ore deposition not only influences efficiency but also reduce the spiral chute service life.The observation found that the ore mainly piles in the middle-lower part of the chute body, and the middle part of the cross-section. The reasons as follows, first of all, the placid chute curve and small inclination angle slow down the flow speed, and weak the fluidity, that easy to cause minerals deposition, especially in the middle-lower part of the spiral chute while mineral preliminary separating. Secondly, unreasonable parameter.
