The pretreatment of uranium ores by physical processing; Les problemes de la preconcentration des minerais d'uranium par voie physique

Abstract

After giving an outline of the classical means of physical processing - granulometry, gravimetry, flotation, magnetism, electrostatics, the authors study the methods peculiar to radioactive ores: pretreatment in batches (counting cylinders) or stone by stone (electronic sorting belt). The three factors to be considered in any treatment operation are studied (cost of the operation, metal recovery, ratio of concentration), as well as their bearing on the cost and the productivity of the following operations. Making use of radioactivity in order to find out instantaneously the approximate grade of the obtained product makes it possible to reduce costs and improve results by setting up total automation.
