analysis and proposed changes of tin ore processing system on .
Tbk. Currently tin ore processing system in KIP produces high grade tin ore (±70% Sn). By applying high grade tin ore processing system in KIP, recovery of tin ore is low and associated minerals of tin contained in concentrates secondary jig will be wasted. To change the processing system to be low grade in KIP be enough.
Processing of low grade tungsten ore concentrates by .
The R and D work carried out on purification and recovery of tungsten as tungstic oxide/ammonium paratungstate (APT) from a number of off grade products such as table concentrate (WO3=66%, SiO2=2·2%, S=1·8%), middlings (1820% WO3, and 2830% S) and jig concentrate (4·6% WO3) are discussed in this paper.Get Price
