phos

Was doing some reading on removing impurities in iron ore while we patiently wait for the met results and stumbled across an interesting study conducted on Agbaja ore using bacteria which got the phos content down as low as 0.25%. Obviously phos isn't the major concern given penalties for high phos ore aren't too bad but an interesting read anyway
