ABSTRACT:
Apparatus and method for selective wetting of particles includes sizing of particles to a preselected size for enabling optical discrimination between desired particles having a relatively large surface area receptive to coating by a preselected wetting agent and undesired particles having a relatively small surface area receptive to coating by the preselected wetting agent. The particles are fed into a conditioning zone defined by the spray of wetting agent from at least one spray means, the spray of wetting agent being in sufficient quantity to impact and coat substantially all of the surface areas of the particles receptive to coating by the wetting agent. The means for feeding the particles into the conditioning zone is disposed outside the conditioning zone and preferably feeds the particles in an unsupported state into the conditioning zone.
