One of my biggest concerns was the development of new and cheaper technologies for producing Hpa. After i found out about the new method of obtaining HPA proposed by Colerina I've done a bit of research and yes,it's been done for quite a few time although i don't have all the details but in the studies i read they where recovering about 6 mg aL3+/l of solution. At the moment i don't know what pregnant solution they use but definitely the Al concentration has to be bigger than 6 mg/l otherwise wouldn't be feasible.
Anyway today we had some numbers coming out and doing some quick calculation our capex/t HPA is about three times bigger than CLL's but surprisingly EBITDA/t HPA on ATC is 27.333 AUD/t and CLL's is 24. 313 . CLL's proposed a 10200t/y plant and ATC 4500 t/y.
In the end we are still ahead.
