1. A hydrocyclone apparatus configured to separate particles from a slurry, the apparatus comprising:
a central body formed by a body wall, wherein the body wall runs longitudinally from a first body opening at one end to a second body opening at another end opposite the first body opening;
a porous barrier coupled to the body wall forming an outer layer of the body wall, wherein the porous barrier allows air or gas flows from a secondary barrier opening to flow through the porous barrier and then between one or more rows of cascades of blades forming an inner layer on an interior side of the porous barrier;
a first volute connected to the first body opening having a first slurry input port forming a first cyclonic opening, a body interface coupled to the first volute and that is attached to the first cyclonic opening that is configured to allow a fluid flow of slurry with particles to the interior of the central body, wherein the particles are separated from the slurry by a froth created by a hydrocyclone formed therein, wherein a central air column is formed within a core of the hydrocyclone;
an air base column coupled to the central air column configured to support the air column and isolate the core having low pressure from a high pressure region near the body wall of the hydrocyclone to prevent the froth from being outputted by an exhaust port;
a second volute connected to the second body opening having a second slurry input port forming a second cyclonic opening, including a body interface coupled to the second volute attached to the second cyclonic opening configured to allow a fluid flow of residual slurry to the interior of the central body and the second volute, an interior wall of the second volute configured to form an exhaust opening configured to receive residual particles to flow residual particles matter to the exhaust port coupled to the second volute configured to allow fluid flows of captured particles matter to the exterior of the apparatus, wherein the air base column allows during operation of the hydrocyclone slurry flows to be expelled from the hydrocyclone apparatus via the exhaust port.
