The 411 on Mining Slurry Pipelines

The mining industry（Industrial Pipes） all over the world makes use of slurry pipelines for transportation of mineral concentrate from mineral processing plants situated close to the mine. The ore concentrates are mixed with water, soon after which it is pumped into pipelines to a website exactly where the mixture is shipped to other areas for additional processing activities.

The use of slurry pipelines gives visible economic benefits when in comparison to transport by railway, specially in conditions exactly where mines are situated in extremely remote regions. Transportation of tailings via slurry pipes also decreases influence on the environment. These pipelines are usually combined with existing railway infrastructures, generally installed above ground, with pipes following the routes from the rail tracks.

Prior to solids might be transported：Before mining solids（Mining Pipes） are ready to be transported, they need to undergo a process of pulverizations, after which the pulverized material is mixed with water to be able to type a paste, or slurry. Through the slurry pipeline, this substance is then deposited into a mixing tank which includes big rotating wheels to facilitate the uniform mixing in the water as well as the particles. Right after this method, the slurry is pumped out by means of the pipeline after which it really is transported over extended distances, powered by special plungers or piston pumps, aided by gravity and different ground level elevation techniques.

Fine and coarse slurry：The substance of finely ground strong particles in liquid is named fine slurry, whereas bigger particles mixed in together with the liquid make up coarse slurry. When transporting coarse slurry in pipelines exactly where - as a way to suspend the solids - the velocity needs to be higher, extensive abrasion for the pipe as well because the pumps can take place, paired with higher energy consumption. For that reason, coarse slurry pipelines are often only economical and sensible when utilised more than shorter distances, often not considerably additional than a few kilometers away from the mine. Conversely, fine slurry is considerably significantly less abrasive and may therefore be transported more than longer distances with no causing also significantly abrasive harm towards the slurry pipes.

Handling extreme abrasion：Slurry pipelines are engineered in such a way that abrasion from solids transportation at the same time as corrosion triggered by the soil is kept to a minimum. For this objective, most pipelines are coated with high-strength polyethylene. The pipelines are produced to be very efficient when it comes to the absorption of kinetic power in the rough particles which are contained within the slurry, and with regards to their resistance to deformation, preventing damage brought on by the transportation process.

What are they produced of? Slurry pipes are typically produced from either coated or bare steel, ranging in size from 80mm -3200mm pipes, using a variety of linings and coatings like galvanized, polyurethane, polyethylene, epoxy, polypropylene and cement mortar.

Common supplies transported in slurry pipelines：Many distinct types of material can be transported in slurry pipelines including copper, iron, limestone, lead, coal, phosphate concentrates, nickel, zinc and bauxite. Following ore processing, tailings from mineral processing plants are also transported through these pipelines, for the objective from the disposal of remaining rock particles.（Pipe Manufacturers）

In the destination：When the slurry comes out at the other finish of the pipeline, components are separated from the slurry by signifies of filter presses which extract the water. Following this process, the water undergoes waste remedy procedures soon after which it truly is either returned to the mine, or disposed of.
