Abstract

En un proceso para beneficiar roca de fosfato se provee una suspension espesa con entre 30% y 70% en peso de una fase líquida y con una fase solida que comprende arcilla, arena, y roca de fosfato. En el proceso, la suspension se expone a energía ultrasonica que se libera desde un transductor de ultrasonido situado dentro de la suspension. La suspension se puede exponer a la energía ultrasonica durante menos de 10 segundos. La energía ultrasonica se puede producir mediante un transductor piezocerámico para que tenga una frecuencia de resonancia dentro del rango entre 16kHz y 100kHz. La energía ultrasonica puede tener una intensidad dentro del rango entre 0,0001 W/cm3 y aproximadamente 1000 W/cm3. La energía ultrasonica puede crear fuerzas de cavitacion dentro de la suspension espesa. Luego de la exposicion a la energía ultrasonica, la arcilla y la arena se separan de la roca de fosfato, tal vez usando un proceso de flotacion en aire y un proceso de ciclon.In a process to benefit phosphate rock, a thick suspension with between 30% and 70% by weight of a liquid phase and with a solid phase comprising clay, sand, and phosphate rock is provided. In the process, the suspension is exposed to ultrasonic energy that is released from an ultrasound transducer located within the suspension. The suspension can be exposed to ultrasonic energy for less than 10 seconds. The ultrasonic energy can be produced by a piezoceramic transducer so that it has a resonance frequency within the range between 16kHz and 100kHz. The ultrasonic energy can have an intensity within the range between 0.0001 W / cm3 and approximately 1000 W / cm3. Ultrasonic energy can create cavitation forces within the thick suspension. After exposure to ultrasonic energy, clay and sand separate from phosphate rock, perhaps using an air flotation process and a cyclone process.
