Walker mining provide diamond mining machine such as : trommel scrubber,high frequency vibrating screen,jig separator .trommel scrubber is popular in washing clay/mud out the alluvial diamond ore . vibrating screen with high quality pu screen is high efficiency in separating and size different diamond ore .jig separator can concentrate heavy minerals such as diamond.e

Except  Diamond wahs plant ,we can also can provide  Diamond  DMS separation plant.

As for the DMS separation plant,  we have two different process flowchart of DMS system for your reference:

1. One type is with Ferrosilicon as heavy medium,use cyclone to separate out diamond.

2. The other type is with jig separator to concentrate diamond which is without Ferrosilicon.

Below is the contrast of  those two different DMS system

Each type has its advantages & disadvantages. Now We make a comparation for more clear
idea. When Checking this document, pls reference to below attachedment:
1. Flowchart of 60TPH Diamond DMS system with jig

2. Layout Picture of 60TPH Diamond DMS system with Jig

3. Flowchart of 60TPH Diamond DMS System with Ferrosilicon

Advantages & Disadvantages of two type diamond DMS system:

1. Total Cost : Price of Diamond DMS system with Ferrosilicon is expensive
expensive than DMS system with Jig
2.  Beneficiation process flowchart:
1) DMS system with Ferrosilicon is more complicated than DMS system with Jig, it includes many slurry pipes and slurry pumps, ferrosilicon input ratio and recycling. According to our  customer experience at ferrosilicon, it  require very professional technical people to check the specific& ratio of ferrosilicon according to diamond ore size and conditions.
2) DMS system with Jig is more simple flowchart, no need ferrosilicon and slurry pipes.
3) 1-25mm  diamond concentrate can be separated out by the cyclone in DMS system with Ferrosilicon. The worker is not able to touch with diamond during the whole system processing.
4) In DMS system with Jig, the diamond concentrate will be separated into 2 parts: small diamond will be continously discharged from under screen of jig , on-screen diamond concentrate will stay above screen of jig , after working some months, need to stop jig machine working, and clean out the diamond above screen. In this way, worker may touch the diamond

Diamond DMS
DMS is the abbreviation of dense medium separation, what is one principal type of diamond recovery technologies.And the other one is Rotary Pan plant.Compare to most of the other minerals, the diamond has a much higher specific gravity(density is about 3.52 g / cm ³ ), so DMS is an efficient initial process to separate diamonds from diamond bearing material, after which the material will be further processes for the final diamond recovery.

DMS benefication is a method of separating ore particles according to the specific gravity difference in the medium with specific gravity greater than water. That is to say, minerals with different specific gravity can be separated from each other in direct current or two-phase fluid by the principle of floating and sinking. The specific gravity of the separation medium is between that of the high and low specific gravity mineral particles. The ore particles with small specific gravity float up and the ore particles with large specific gravity sink.

Diamond DMS Plant
Ferrosilicon(an alloy of silicone and iron) will be suspended in water in a DMS plant. Then it will form a fluid that is close to the density of diamonds (3.52 g / cm ³). If the ideal density is reached, the diamond bearing material is added to begin the separation process. Due to the gravity, the heavy minerals sink to the bottom, while the lighter material will rise to the top. This is an effectively process to separate diamonds from other material.

Diamond DMS Washing Plant
The commonly used beneficiation methods for diamond are: washing pan, jigging, DMS, X-ray electric, ointment, surface flotation, magnetic, electric, flotation, hand-selected, etc.,

The beneficiation process of primary diamond ore mainly depends on the properties of the raw ore, the scale of the concentrator and other factors. The reasonable technological process mainly considers the protection of diamond crystal from damage or the minimum damage; To determine the reasonable number of crushing sections and the appropriate sorting. The maximum recovery of mineral processing and comprehensive recovery of fine-grained diamond and useful associated minerals are obtained.

The roughing process of diamond placer is simpler than that of primary ore. It does not need multi-stage crushing and grinding and multi-stage separation process, but only needs washing, screening and desliming to enter the separation process.

The concentrate process of diamond placer and primary diamond is basically the same. Generally, the coarse particles (less than 30mm) are treated by X-ray electric separation, grease separation, selective grinding and screening, manual separation and other methods. Surface flotation, magnetic separation, electric separation, selective grinding and screening are used to treat medium size (less than 3mm). Fine grain (less than 1mm) is treated by chemical treatment, froth flotation, magnetohydrostatic separation and heavy liquid separation.

Diamond DMS Washing Plant Flow

Diamond DMS Washing Plant Flow

The above flow chat of diamond mining plant contents three parts: washing, crushing and separating. The material enter into the vibrating feeder, through it, the material less than 70mm enter the diamond washing trommel scrubber. After the washing, the particle size greater than 25 is sent to jaw crusher for crushing, and the particle size less than 25 mm is sent to vibrating screen. And then the concentrate of vibrating screen is separated by jig separator.

Diamond DMS Washing Plant Equipment
Trommel Scrubber: Good Effect on Diamond Washing Plant
Diamond ore usually has clay or a large amount of mud, so it is necessary to clean it before separation. Trommel scrubber has a good effect on washing heavy clay or viscous clay. Therefore, it is widely used in diamond washing plants.

High-frequency Vibrating Screen: Screening and Dehydration
After washing the diamond ore, it is necessary to classify the size of the ore. Filter out the size of the waste, and then transport it to other places with a belt conveyor. The particles under the screen will enter the next process.

Jig Separator: Common Used in Diamond Plant
The jig separator has a good separation effect on diamond, and it is widely used in diamond separation devices.
