Sr<rtl point* remain to bo studied on tbo improvement of ths bariua hydroxide process. CoffeyviUe hu used stranger sulfide liquors recently sad believes this has laproved ths conversion. It is not known how far this process can be carried and what would be the maxlaua concentration at which we could operate. Vo oan try out higher strengths of bariua sulfide solution aad learn the affects. We will also do sows further study and consideration of the possibility of using --onls as an intermediate in a new process for manufacturing bariua hydroacid*. On the chloride Modification, two or threw additional recyclings will be aede to extend our series, which Is now seven cycle* in lsngth, to show ths eontinuliK reactivity of recycled copper oxide. 6. 2DC OXIDE COPPgt REMOVAL. This project will be continued and worked up into a process idiom re coveries and losses can be estlaated nor* closely than at present. Iks possibility of recycling the cyanide solution will be proved or disproved, as well as ths determination of aatsrlsl balances. Anaconda funs as wall as Bunker Hill fuas is to be tried. 7. VANADIUM ANTIMONY TITANIUM GHAT. Additional experiments will be aade to find how to wake this material in the rotary kiln. A an--ry of other available colors and our present status on each of than will also be prepared. 8. L3ADKD 2DC CHIDE - COLCKB). A proposal will be worked out and submitted concerning colors which might be developed. 9. scpnai Kzaasigjrm (s o d iu m d u h io mt e ) As a high priority itsa, a brief survey will be made of the chemistry sad ecnaradio of maaafbeturlng sodium hydrosulfite with sine oxide as a by-product. A report will be written and submitted, and a possible future experimental program will be presented. 10. BARIUM CARBONATE. Although CoffeyviUe is to have the major responsibility for making a technical and economic study of the various processes for bariua carbonate, our laboratory will cooperate with this and help in any ways which may be appropiate.
