PATENTE 00T 18 1870 Fga.. 0W WMM limiten. Sintes CYPRIEN MARIE TESSIE DU @Arent @irriteQ Horny, or rniiis, FRANCE.
Specification forming part of Letters Patent No'.l B GAJSQ, Vdrifted October 1S, 1870.
To di whom 'it may concern:
Bo it known that i, CYPRIEN MARIE Tits- SIEDU Mo'iAY, of Peris, in `the Empire of France, have invented c new vimfproyement in TrentingCopper Pyrites; andi do hereby declame the following, when teken in connection with the'eccomponying drawings end the letters ot' reference'vmerked thereon, to be' n full, clear, and exact description of the same, and. which said dra-wings constitute part oi this specification, end-represent, in
Figme 1, a. longitudinal sectioin'end in Fig. 2 s transversesection.
` This invention hns for its object n, new process fortnetrentnient ci' copper pyrites. This process produces e radical transiormstion in the operations in use for the roasting ot' these ores; ond it consists in roasting thepre when in a mreltefl'staieliy means of air or oxygen, which nt the saine time performsn mechanical mixing oi' the materiels in an apparatus specially designed for the purpose.
lrcvionsiy introduced in e iiquidstate into itcnp'oln, H,'the ineited ore is conveyed oy a 'mindesten i, into the eppnrntns for roasting nml mixing. This spp-nietos is composed of [we chambers, A A', communicating by a pessngc, B, between them. A certain nnmncr of tubes, U U U, convey into the midst of the melted mass'currents oi' eiror oxygen', and, it' it is necessary, simultaneously mingled currents of air and combustible gas.
The openings D- i) for the @scope of the gas (azote, snlpliurons acid, 8vo.) may icc alternately closed, and. the inlets E E bring air onder pressure into the upper part oi' the chambers A A', governed by suitable valves, to prod nce upon the melted mass a pressure sometimes upon one side and; sometimes upon the other, which forces the seid mass through the passage B alternately into one or the other of the chambers A and A. This alternate compression causes a. regular mechanical mixing during the Qessege ot the mass, the more so as the difference ot' density of the several parts acts concurrently to produce al close mingling and facilitate thechemicel reaction produced by the air, oxygen, or gas,
The discharge is eiiected through the open ing F when the roasting is sulcientl y advanced.
The mass obtained is remelted in the cupole and alge-in roasted in the saine apparatus, end
theseoperationsare successively repeated a eertain number of times. Aneddition of silica is employed in proper proportionsv according to the natnreof theore, to scnrify the side ot' iron produced during the roasting. Mattes are in this manner obtained very' rich in copper, and il: only remains to reduce andrene them.
The apparatus before described may be modified without changing the principle of ccnstruction. y
it is 'understood that various means may ne adopted for closing the orifices G for filling and F for discharge, and for the arrangement Iof the` openings D D for the escape of the ges, ,for the notaire of the materialsused in the pron cess are essentially variables-nd maybe trented in the wey which practice may prove most advantageous.
it is optional to varythe forni, materiaal, and dimensions ofthe apparatus founded upon the seme principlee i claim as my invention;-
lhe process herein described for treating copper pyrites, consisting of'zt simultaneous pneumatic mixing of the melted ore by means 'of the aiternate compression ot' nir or oxygen,
with or without the presence of combustible A,substantially in the manner herein set forth,
in testimony whereof i have signed my neme to this specioation before two subscribing witmesses.
