staying "on the grind" means to work hard, always be hustling, or otherwise engaged in money-making or woman-procuring activities. people who were once poor and become wealthy might then become lazy and indolent and spend all day in champagne-filled jacuzzis whereas other newly-successful people might continue to work hard, thus "staying on the grind"

The Kubaka grinding circuit was designed using SPI calibration work (originally presented at the SAG '96 conference), perhaps the first such installation to be planned using these calculations. O ne key to using SPI during the design of a grinding circuit, is to use the value of the hardest ore, not an average hardness.
