Page 124 - The height of discharge may be defined as the vertical distance from the top of the die to the bottom of the opening of the screen-frame.
Page 232 - This arrangement of separate clutches for each pan and settler is very convenient, as any number or any one pan and settler can be stopped in case of accident for cleaning out, without having to stop the whole line.
Page 429 - The separation is due to the fact that zinc has a greater affinity for gold and copper than for silver.
