SOLIDS CLASSIFICATION PROCESS

摘要

A process for classifying a crystal mixture or for concentrating rocks or mixed crystals in particle form by capturing the particles in a gas flow for the purpose of separating particles of different size and weight by means of natural or artificial gravity is disclosed. The particles are heated to a temperature so high that a difference sufficient for separation is obtained in volume or weight between different particles. For spodumene, quartz and feldspar this temperature is about 1000 DEG C.
