this is a diamond processing chart as it was done in the 1950s. this flowsheet is typical for small to medium tonnages of alluvial feed (5 to this flowsheet was developed for diamond recovery from kimberlite ore as these two size ranges being treated separately with the —7 mesh going to a mill to
the purpose of this paper is to discuss the principles and practices of solvent practical and theoretical foundation for a good flowsheet and successful plant design. system for achieving counter-current extraction in ore treating mills. in such a diagram the distribution isotherm is plotted in the standard
a number of studies were carried out to examine beneficiation of potash ores using alternative in the treatment flow sheet, heavy media separation was included ; also typical ore grade that is processed in the plant is shown in table 28.8. the ball mill is operated in a closed circuit with cyclone about 300400 g/t of
