Opening rate: 35% or as your need.(opening rate = slot size / slot size + width of the profile wire)
Application：Interstage screen is used during the concentration stage, recovery of precious metals in gold and silver mining. MPS & MPS(P).
Interstage Screen In CIP and CIL Process
CIP – Carbon In Pulp. First leaching, and then adsorption.
It is suitable for the treatment of oxidized gold ore with low sulfur content and mud content.
The gold cyanide complex is adsorbed onto the carbon until it comes to an equilibrium with the gold in solution, the coarse carbon is then separated from the slurry by a V wire interstage screen.
Application: Flotation of gold concentrate or mixed mercury, gravity tailings, argillaceous oxidized ore.
CIL – Carbon In Leaching. leaching and absorption are simultaneous.
Each absorption tank is provided with a carbon wedge wire wrapped interstage screen to separate carbon and slurry.
After screening and washing, the gold loaded activated carbon will be sent to the desorption operation.
The carbon isolation screen shall be installed at the outlet of each absorption tank, and the screen generally adopts a 304 Johnson screen mesh.

Our Wedge Wire Intertank Screen Advantage
- Quality raw materials
Our factory is located at the source of stainless steel wire mesh, which can control the quality of products from the source. Has excellent corrosion resistance and wear resistance.
- Advanced welding technology
We use the most advanced circular fusion welding technology at present, and the welding position of the wedge wire (vee wire), and the bracket is stronger.
- Product customization
We have 6 sets of advanced Johnson screen production equipment and related supporting equipment, a strong technical team has the ability to customize products of various specifications for customers.
- Patented surface cleaning technology.
Physical cleaning technology makes the product more resistant to corrosion and improves its service life.
304 stainless steel VS 430 stainless steel (for interstage screen & intertank screen)
430 stainless steel contains 16.00-18.00% chromium and is basically free of nickel metal.
304 stainless steel containing chromium-nickel.
Therefore, 430 stainless steel is not as good as 304 stainless steel.
- Stable performance.
430 stainless steel is ferritic, 304 stainless steel is austenite, 304 stainless steel is more stable than 430 stainless steel.
304 stainless steel has strong toughness, which is stronger than 430 stainless steel.
- Mechanical behavior.
430 stainless steel adds stable chemical element titanium, the mechanical properties of the weld are better than 304 stainless steel.
Comprehensive comparison, 304 stainless steel is more suitable as a raw material for the interstage screen.
The performance of 316 and 316L stainless steel is better than 304 stainless steel, but the cost is higher, and customers can choose suitable raw materials according to specific conditions.
The choice of material is very important, the wedge wire intertank screen needs to have excellent corrosion resistance, and the layer does not help it improve its service life.
According to our accumulated end-user data, stainless steel 304, 316, or 316L is the best choice.
Our mission is to provide the mining industry with high-quality customized production services of Johnson screen products.
Intertank cylinder screen is our most successful product in the gold and silver mining industry, we can provide OEM & ODM services to customers all over the world.
Sawdust, grass roots and other debris in the slurry can easily cause clogging of the pipe and screen, and the sawdust will absorb gold, so it must be removed before leaching.Bluslot™ – China Continuous Slot Wedge Wire Screen Manufacturer.
We provide rotary drum screens for the first impurity removal process.
