Selektywna flokulacja chromitu i serpentynitu
Języki publikacji
Abstrakty
Application of selective flocculation using starch to separate chromite from serpentine has been investigated. It was determined that starch has a specific affinity towards chromite which can be exploited in selective flocculation. However, it was found that this could only be achieved when the amount of serpentine in the chromite-serpentine mixture is below 30% by weight and in the presence of a dispersant such as sodium silicate or ultrasonic treatment of the pulp.
Metoda selektywnej flokulacji z użyciem skrobi jako flokulanta, została użyta do oddzielenia chromitu od serpentynitu. Zostało ustalone, na podstawie badań, że skrobia wykazuje specyficzne powinowactwo do chromitu, który dzięki temu może ulec selektywnej flokulacji. Okazało się jednak, że selektywny rozdział jest możliwy do osiągnięcia w warunkach, gdy ilość serpentynitu w chromicie nie przekracza 30% wagowych. Proces separacji został zrealizowany w obecności dysperganta - krzemianu sodu, a zawiesina była traktowana ultradźwiękami.
