Abstract
<PICT:0412511/III/1> Boron minerals of the class containing mainly rasorite and some tincal are subjected to progressive magnetic separation, whereafter the concentrated minerals are calcined, say at 230--250 DEG F. to obtain a product containing say 25--27 per cent of water which is stable when exposed to the air. The mineral, comprising rasorite and tincal, shale, and tramp metal may be passed successively over rapidly rotating rotors I, II and III. The first two rotors are connected in parallel and are in series with the third, whereby the flux supplied from electromagnet 50 increases progressively. The mineral is supplied tangentially to the rotors, which are provided with non-magnetic areas to assist the separation. Passage over the first rotor serves to remove tramp iron a, most of the shale g is removed by the second rotor, whilst the third rotor separates the mineral into shale b, a mixture b, c, d of shale, tincal, and rasorite, and a mixture c, d of the boron minerals. Mixture b, c, d is re-run through the machine, whilst mixture c, d passes to a rotary drier H, which is heated by hot gas or air supplied at T.
