PROJECT 1
Characterization of OPS Slag
Using Leitz reflected optical microscope under high-resolution beam.
The dessiminated copper relicts are visible in many silica rich granules. As shown in following photomicrograph. The copper is commonly observed in -52 mesh powder. The pohotomicrograph is taken in 20X10 x magnification in plane polarized incident light.
Grains of BISMUTH are at times reported in slag, showing polysynthetic twinning and rapid oxidation.
EXECUTIVE SUMMARY
Both the fractions of slag i.e., +52 and -52 # powder are subjected for ore microscopy for determination of optical characterization and granulometric assessment of economic metal-bearing particles.
Both the sample have denoted the existence of silver, copper, lead (litharge) and traces of bismuth metal in exsolution blebs, dendritic texture, individual specks, eutectic point of crystallization and triangular equilibrium state between silver and copper of assorted sizes, slow and rapid cooling both type of crystallization are reported.
All the other details of texture and grain sizes are:-
+52 Mesh -52Mesh
Ag 23.59 % 26.90 %
Cu 7.52 % 13.04 %
Pb 12.40 % 8.38 %
Bi 1.85 % 2.16 %
