PROJECT 4
Stream survey and analysis campaign
Half-Hourly composite samples over two-hr continuous operation at 19 selected points in Pb & Zn circuits for - chemical assays - particle size distribution - pulp density - mineralogy
Size distribution in Pb circuit
Mineral liberation details
Liberated Sphalerite of over 75 microns are commonly observed along with free and locked sphalerite of 50-75 microns along with Graphite are noted.
Size distribution in Pb circuit
SUMMARY
Major details in the survey samples:
Feed
-
Feed has been observed with Gn 50% and Spl 81% as liberated phase, while both minerals are commonly locked with Gangue in a complex mode
-
...
Pb Concentrate
-
Gn 89% free while liberated Spl is 52 %. Sphalerite occurred relatively coarser than the galena as is placed free grain.
-
...
Pb Tail
-
Galena & sphalerite as liberated at 6% & 75 % respectively.
-
...
Zn Concentrate
-
Minor amount of liberated gr & gangue is noted up to an extent of 1.60% & 3.9% by volume.
-
...
Final Tail
-
Liberated Sphalerite occurs upto 0.88% by vol and 23% of sphalerite in sample is liberated.
