The invention relates to a magneto-centrifugal flotation cell for ore concentration which reduces water consumption. A disadvantage of conventional flotation cells is the use of a large amount of water, some flotation cells requiring at least 60% water. The present invention uses ore pulp with increased density and viscosity, owing to the application of an axial magnetic field, wherein the Lorentz force, which is the force exerted by an electromagnetic field that receives a charged particle or an electrical current, can be used. The solution is a cell which, in addition to the forces that usually act on conventional flotation cells, uses external forces which, in principle, produce synergy in the separation of ore particles that have different gravitational and magnetic properties.

An automatic purification system using magnetic particles comprises: 1) a first container module; and 2) a system controller module. The first container module comprises a first container and a first magnetic field supply device disposed outside the first container. A first container liquid inlet is formed in the upper portion of the first container, and a first container liquid outlet is formed in the bottom of the first container. The system controller module can generate a variable magnetic field in the first container by controlling the first magnetic field supply device. A method for purifying a target component from a biological sample comprises a step for allowing a biological sample containing a target component to be in contact with magnetic particles capable of specifically binding the target component, in the first container in the automatic purification system. The automatic purification system and method help to efficiently separate a target product from a biological sample, and helps to reduce process costs and time at the same time.

A basket strainer insert having a body with one or more magnets disposed therein. The basket strainer insert includes a baffle that is removable. The movement of withdrawing the baffle from the body allows magnetic debris to be removed. A baffle may be disposed at the center of the elongate intermediate portion of the body. The baffle may comprise a collar and two or more symmetrical lobes, each lobe comprising an upper portion and a lower portion. Alternatively, the baffle may be a hollow shape with a plurality of apertures.
