A review of cassiterite beneficiation fundamentals and plant practices

Particle size analysis indicated that 96% of the feed material is finer than 20 μm and 30% is finer than 5 μm. It is reported that the flotation efficiency was very low for the cassiterite particles <5 μm.

Cassiterite beneficiation in China: A mini-review SpringerLink

Abstract. Tin is indispensable for the development of advanced technology and cassiterite is the only mineral of commercial importance, from which tin can be extracted economically. In the past two decades, tin reserves in China have experienced a rapid decline because of active mining activities; simultaneously, cassiterite This work investigated the hydrophobic flocculation of cassiterite using four alkyl hydroxamic acids with varying carbon chain lengths, i.e., hexyl hydroxamate (C6), octyl hydroxamate (C8), decyl hydroxamate (C10) and dodecyl hydroxamate (C12), as collectors.
