· 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 …

· An adsorption model was proposed to explain the improved collecting ability of Fe-BHA complexes for cassiterite flotation. In this model, when FC and BHA were sequentially added in the pulp, the hydrated cassiterite surface can firstly form compact Fe-hydroxide layers, which hindered BHA to adsorb on the hydroxylated cassiterite surface.

· Tin mineralization is mainly in the cassiterite greisen, cassiterite–tourmaline–quartz, and cassiterite–quartz vein stages. The deposit is characterized by widespread tourmalinization.

The results provide strong evidence that the tools were used in cassiterite processing. The combined analysis of these artefacts documents in detail the exploitation of Cornish tin during this early phase of metal use in Britain and Ireland.

This mineral is found in hydrothermal veins and pegmatites associated with granite intrusions. Because of its durability, it is also frequently found concentrated in alluvial placer deposits, sometimes in large enough quantities to be commercially exploitable, as in Malaysia, for example. May precipitate from volcanic gas, as shown by ...

· The Nanyangshan pegmatite host abundant spodumene, lepidotite, beryl, cassiterite, columbite and tourmaline and can be roughly divided into black tourmaline (Tur B)-cassiterite and pink tourmaline (Tur P)-spodumene bearing phases. Most of the cassiterite are homogenous in appearance although some (<10 %) have core-rim …
