How Does Interstage Screen Work?
Mineral processing separating pumping and mineral processing separating is a type of top submerging exit screen that aids in carbon leashing.
Normally, the interchange screen will be submerged under the pulp solution at the operating levels.
The pulp solution flows through the interstage screen while retaining the carbon on the outside.
After separation, the pulp flows inside the Interstage screen.
Then through the launder interface on the volute interface and the wedge wire screen.
Both mineral processing separating pumping and mineral processing separating works differently.
Ideally, mineral processing separating pumping installation occurs in circuits.
This is where by the pulp levels and tanks are all at the same horizontal levels.
Mineral processing separating pumping operates at a lower pulp pressure than that of the pulp at the exit launder.
During this operation, there is always a pressure drop.
It should be minimized by an up-pumping impeller that is incorporated in the interstage screen.
The up-pumping action increases the pulp velocity and head for transporting the pulp to the next adsorption tank.
The advantage of mineral processing separating pumping is that;
It works on a horizontal level rather than a conventional cascading operation.
Mineral processing separating is utilized in circuits where the tank’s arrangement is in a differential arrangement or a cascading arrangement.
The differential height compensates for the pressure drop which allows the pulp to flow into the interstage screen.
Normally the mineral processing separation operates with a pressure that is relatively low to that of the pulp at the exit launder.
Note both mineral processing separating and mineral processing separating pumping are easy to clean and maintain.
This is because they form an integrated unit that is easily removable for regular cleaning and maintenance.
How Does Carbon-In-Leash Compare To Carbon-In-Pulp In Interstage Screen?
Normally interstage screen operates concurrently using the carbon-in-pulp and carbon-in leash operations.
These operations help separate the gold ore from the activated carbon.
Carbon in pulp
Carbon-in-leash and carbon-in-pulp are both applicable in the interstage screen during gold adoption and carbon leashing.
For carbon-in-pulp, the first activity involves leashing and then adsorption of the gold.
In carbon-in-leashing involves simultaneous activities of absorption and leashing of carbon.
As the extraction takes place the interstage screen is enhanced with a wedge wire which separates the carbon from the slurry.
In both carbon-in-leash and carbon-in-pulp involves a series of operations that occurs simultaneously from one tank to the other till the last tank.
Carbon on the other hand flows concurrently from the last tank to the first one which prevents mixing or blocking of the interstage screen.
Both carbon-in-leash and carbon-in-pulp methods,
Normally the adsorption tanks are arranged on a horizontal same level or a convectional cascading sequence.
The difference between carbon-in-leash and carbon-in-pulp;
It is to what extent the leashing of gold takes place before the adsorption of carbon.
During carbon-in-leash addition of carbon takes place simultaneously into the leashing tanks.
This means that the leashing and adsorption of carbon take place all at once. Simultaneous absorption and leashing help to curb the reduction of the gold ore that is normally meant for activated carbon.
But in the case of carbon-in-pulp leashing of carbon takes place before the adsorption of the carbon.
In most cases, the carbon-in-leach operates with a maximum of 6 to 10 adsorption tanks.
In What Size Can You Get The Interstage Screen?
Ideally, there is no standard size when it comes to the interstage screen.
The interstage screen comes in different sizes depending on what a client wants and the intended purpose.
We have an Interstage screen with different size slots, wire width, aperture size, and different lengths.
All these aspects reflect the final throughput of the pulp and carbon leashing by the interstage screen.
The size of the interstage screen varies from 500 to 100 microns, this gives you a wide option to choose from.
Normally we work with the sizes that the clients suggest to achieve quality and meet our clients’ requirements.
How Do You Choose The Right Interstage Screen Size?
To determine the right side of the interstage screen,
It’s important to first consider the following aspects the slot size and the wire width.
Normally, the aperture size of the interstage screen depends on the range of carbon size.
Aperture sizes are available in all standards which include the cylinders.
To ensure continuous tolerance of the apertures control instrumentation and advanced measurements measures should always be put into place.
For instance, the carbon-in-pulp has a high release angle which improves the open area thus resulting in higher throughput of pulp flow.
It also results in minimal blinding of the interstage screen.
Is Interstage Screen Durable?
Yes, the interstage screen is very durable.
The interstage screen is made of stainless steel.
Stainless steel has very high-quality features such as high resistance to corrosion and abrasion.
It’s also a tough metal which means it cannot
Be damaged by the outside and inside pressure exerted but the pulp and the carbon leash.
How Does Mineral Processing Separating Compare To Mineral Processing Separating Pumping Interstage Screen?
Mineral processing separating and mineral processing separating pumping are two technologies that apply in carbon leashing.
Mineral processing separating and mineral processing separating pumping contains a wedge wire screen which is submerged under the pulp operating system.
After the installation of these interstage screens the pulp normally flows upwards while retaining the filtered carbon on the outside.
Mineral processing separating interstage screens is normally utilized in circuits where the tanks have been installed in differential heights.
Normally, the height differential concept helps to overcome a pressure drop. This intern allows the pulp to flow through the plant.
Ideally, the pulp levels should be relatively higher in the tank than in the pulp exit launder.
Mineral processing separating pumping interstage screen is initially installed in circuits.
In this Interstage screen, the pulp levels and tanks are both on the same level that is the horizontal elevation.
To curb the pressure, drop, an upcoming impeller should be incorporated around the mineral processing separating pumping.
This impeller pumping process allows the pulp to move from one tank to the next tank.
Both mineral processing separating the interstage screen and mineral processing separating pumping has an integrated unit.
This integrated unit comes from the screen and the drive which is so easy to remove for regular cleaning and maintenance.
Mineral processing separating pumping operates on the same horizontal level of operations.
This makes it better over the mineral processing separation as it requires minimal civil construction requirements.
How Much Does Interstage Screen Cost?
