outcome is poured into normal water collected in steel pots. Thereupon the melted steel and gold mixed solidifies to some extent and the same can be taken from the water as a lump. This lump is thereafter collected and placed in a steel vessel to which concentrated nitric acid is added. Upon such addition of nitric acid, the impurities left out, if any, are removed and the gold and silver are separately left over. The gold in sand form is collected and cleaned using water to remove the acidic content if any. Thereafter the gold is again melted and the melted gold is poured into a block to obtain the shape gold bullion bars. The silver which is also left over as above is separately collected and kept aside. The gold bar so obtained in bullion form is traded by appellant as above. In the invoices raised by appellant, he is describing the above commodity as "standard gold (purity 999)". The purity of the above standard gold is 99.9% and the said bullion is purchased by jewelleries like Bhima and used to manufacture gold ornaments thereafter.”
