Computer modelling of primary spiral circuit at South Crofty, Ltd., Cornwall, England
نویسندگان
چکیده
A typical South Crofty ore containing minor amounts of arsenopyrite and chalcopyrite (ore A) gives 65% overall recovery of cassiterite in the spiral circuit, overall enrichment ratios being about 25-35. Maximum recovery occurs in the size range 53-110 /Lm(Fig. 2). However, recently treated ore types (ore B) have been much richer in sulphides, yielding up to 30°" As in the recleaner table concentrate--compared with Table tailings Cleaner spiral concentrate

The Red-billed Chough Pyrrhocorax pyrrhocorax has a restricted range in Britain and has been in long-term decline since at least the early 1800s. Southwest England was a former stronghold and Cornwall was the last county in England from which it was lost as a breeding species, the last successful breeding attempt being in 1947.The reduction of suitable foraging habitat owing to changes in the m...

OBJECTIVES To evaluate 3 pilot chlamydia retesting programmes in South West England which were initiated prior to the release of new National Chlamydia Screening Programme (NCSP) guidelines recommending retesting in 2014. METHODS Individuals testing positive between August 2012 and July 2013 in Bristol (n=346), Cornwall (n=252) and Dorset (n=180) programmes were eligible for inclusion in the ...
متن کاملPhysical Modelling and Particle Swarm Design of Coplanar Waveguide Square Spiral Inductor
This paper presents simple lumped element equivalent circuit for the coplanar waveguide (CPW) square spiral inductor. The circuit is based on physical modelling which takes into consideration the parasitic effects inherent in the CPW spiral inductor. The obtained scattering parameters are in good agreement with fullwave and quasi-static results available in the literature. Such a simple circuit...
متن کاملPrediction of effect of fine particle removal on efficiency of a spiral circuit by size-by-size partition curves
Partition curves are widely used to determine the spiral separator efficiency. In this work, the partition curves were used in order to investigate the particle transportation to concentrate and tailing streams. Simulation of fine particle removal using the size-by-size partition curves showed that the recovery of gangue particles to concentrate can decrease 8.7%. It also showed that the recove...
