摘要： An apparatus for recovering a desired fraction of a raw material bearing the desired fraction has a vessel or cell defining a treatment chamber therein, with an inlet into the chamber for introducing a slurry of raw material to be treated into the chamber. An attrition zone is defined in a portion of the chamber proximate the inlet in the flow path of material introduced into the chamber, the particles being caused to impact against each other in the attrition zone to cause attritioning thereof. A floatation zone is defined in a distal portion of the chamber, in flow communication with the attrition zone, in which attritioned particles from the attrition zone can be contacted with gas bubbles to form a froth phase separated from the slurry by a slurry-froth interface such that the desired fraction is either selectively taken up into the froth phase by the gas bubbles or selectively left behind in the slurry. An outlet from the chamber for the froth phase is present.

摘要： A process of separating a desired constituent from a mixture of particulate matter including the steps of: conditioning a liquid mixture of particulate matter with a frothing agent to create a pulp; aerating the pulp to generate a float fraction of froth supported on the surface of a non-float fraction of pulp; separating a portion of froth from the float fraction; draining the separated froth; washing the separated froth with a liquid to dislodge particles comprising one or more of non-selectively attached, entrained, and entrapped particles; and recovering the washed froth, is disclosed herein. Also disclosed herein are a froth cleaning apparatus and a froth flotation apparatus for separating a desired constituent from a mixture of particulate matter. The froth cleaning apparatus includes a hood including a lower peripheral edge for interface with the top of a froth flotation cell; a discharge orifice disposed in the hood; a froth support in communication with the discharge outlet for receiving and supporting froth; and a wash sprayer disposed upstream of the discharge orifice. The flotation apparatus includes: a wall defining a flotation cell; an aerator for aerating a mixture of particulate matter to produce froth; a feed opening for introducing a mixture of particulate matter and/or froth into the cell; a discharge orifice in a wall of the cell; a froth support in communication with the discharge outlet for receiving and supporting the froth; and a wash sprayer disposed upstream of the discharge orifice.

摘要： An improved flotation separation apparatus for separating and classifying diverse, liquid-suspended solids having a plurality of high volume air bubble infusers. Each infuser includes a circular cavity defined by an interior circumferential wall. A plurality of stationary impinging plates projecting from the interior circumferential wall into the circular cavity and equally spaced circumferentially in series therealong. An injecting stream of water and air impinges upon the impinging plates in series to repeatedly create, divide and subdivide air bubbles as the injection stream transverses the series of impinging plates.

摘要： Disclosed herein is a method for the removal of organic and inorganic contaminants from contaminated sediment or soil. The method comprises a first step of removal and disposal of very large debris while the smaller particle flow is directed to a second step of removal of organic contaminants preferably by means of attrition cell, conditioning tank and flotation columns, the remaining particulate flow, free of organic contaminants, is directed to a third step of removal of inorganic contaminants preferably by means of hydrocycloning to separately deal with very small particles of less than 20 microns, both particulate flows are then preferably subjected to column flotation to separate out the inorganic contaminants. Thus, the method of the present invention yields decontaminated soil or sediment and two distinct contaminant concentrates (organic and inorganic, respectively). Both concentrates can be recovered and used for various applications.

摘要： The invention uses machine-vision to improve the performance of a flotation operation to provide a substitute for conventional human vision and problem-solving abilities. The invention redirects the conventional approach of “characterizing the froth” to “measuring the froth characteristic.” The invention provides a method of monitoring and controlling a mineral mixture flow in a froth flotation cell of a flotation plant which includes the steps of obtaining a series of digital images extracted of froth characteristics from a flotation cell. The digital images are transmitted to a computer for processing thereof into parameter signals of digital parameter froth characteristics. Control signals are produced in response to parameter signals received for causing required variations in froth characteristics in a flotation cell; and the froth characteristics in the flotation cell are controlled in response to the control signals so as to cause required variations in the froth characteristics in the cell.
