of gold process operating costs. As an illustration, for a gold ore grading 2.3 g/t, a 1% increase in gold recovery generates incremental revenue of about $1/t-ore at a gold price of $1,300/ oz. For cyanide at a price of $3,600/t delivered to a remote mine site, it takes only 0.28 kg/t-ore consumption to equate to $1/t-ore, or 1% gold recovery.

Design, fabrication and testing of a millet thresher.
A thresher was developed for threshing, separating, and cleaning millet seeds. The major components of the machine include threshing, separation and cleaning units. The threshing operation is achieved by rotational motion of a cylinder fitted with beater pegs above a stationary grid which results in the removal of the seeds from the panicles and their separation from the …
