Recovery by Flotation of Cassiterite

Surface chemistry and flotation of cassiterite in the presence of alkyl   hydroxamic acid/salt surfactant has been investigated. Results of the   adsorption isotherms, electrokinetic and infrared spectroscopy indicate   that octyl hydroxamate adsorbs on cassiterite by both physical and   specific forces. Adsorption of the surfactant was high in the acidic pH   range indicating the involvement of octyl hydroxamic acid molecule    and uncharged or/and moderately negatively charged cassiterite in the   sorption process. Based on the experimental observations the possible   modes of sorption were discussed.Recovery by flotation of cassiterite  was studied   with alkyl hydroxamates of carbon chain length 8, 10 and 14 on different   sizes of particles.

 

Recycling Crusher 

Crushing in the actual construction site using portable recycling crushers reduces construction costs and also the pollution generated in comparison to transporting material back and forth from a quarry. Large road-portable plants can crush concrete and asphalt rubble at as much as 600 tons per hour or even more. Scalping systems normally consist of a rubble crusher, side discharge conveyor, screening plant, along with a return conveyor from the screen towards the crusher inlet for reprocessing oversize materials. Compact, self-contained mini-crushers are also available that will handle approximately 150 tons hourly and fit into tighter areas.

 

Tailings Disposal

Let concentrator tailings sent to the designated place stockpiling or use of the technology. Each year the tailings discharge concentrator not only quantity, some still contain temporarily not useful components of the recovery. These tailings such as optional emissions, will be for large area farmland, siltation of river, environmental pollution and cause resources loss, which must be properly recycling construction and demolition wasste. For processing in the construction of the tailings structures system called tailings facilities, it is mining development indispensable constituent part. Tailings treatment used more tailings stockpiling method, a condition when the enrichment tailings tapered stockpiling method, although available quarry goaf and tailings filling the comprehensive utilization, but used by the tailings only part of it, the rest of the tailings still need to send the tailings storage.
