What are the key factors to successful spodumene flotation?

The most critical prerequisite for the success of spodumene flotation is the activation of spodumene minerals. The activation process generally includes: desliming, ore washing, strong alkali stirring, etc. The reason for this is mainly because a large amount of iron, aluminum, manganese and other metal ions will contaminate the mineral surface during the weathering process of Li pyroxene, and the resulting fine mud Adsorbed on the surface of limestone, if not activated, the collector is difficult to capture. The normal operation is to concentrate the pulp and add sodium hydroxide, and then de-slime after vigorous stirring for several hours. In normal flotation, under alkaline conditions, fatty acids are trapped. Both amine collectors and amine collectors can be used for flotation, and the specific effect needs to be confirmed by mineral processing tests.
