Abstract: 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.

Abstract: A diagnostics apparatus for detecting fluorescence events related to the presence of an analyte in a sample is disclosed. The apparatus includes a housing, a source of excitation light and a photodetector, and a unitary multi-surface optical module. The optical module is integrally formed and composed of an upstream portion having a focusing optical surface for directing excitation light from the light source to a focal region within an analyte-detection zone in the apparatus, and a downstream portion having a second focusing powered optical surface and at least one reflecting surface for directing fluorescence-emission light produced by fluorescence events within the detection zone, in a direction substantially normal to the path of the excitation light onto the photodetector. The optical module is adaptable to a variety of assay formats, including multiple-sample, sample-array, and disposable-cartridge formats.
