• Lapping and Polishing Basics

    grinding process must be a balance of material removal and subsurface damage. In many cases it is advisable to initially cut the specimen with a gentle mechanical method such as a wire saw. A properly prepared wire saw cut sample can eliminate the grinding process altogether. : Lapping Lapping is the removal of material to produce a smooth, flat, unpolished surface. Lapping processes are ...

  • Gold's new golden moment

    "Many existing refractory operations have lowgrade stockpiles that are waiting to be processed at the end of the mine life. By adding ROL pretreatment to an existing operation, it could become viable to process lowgrade stockpiles earlier, rather than processing them at the end of the mine life. Reducing the cutoff grade, you can move those ounces forward to generate cash flow earlier and ...

    However, certain conditions require that a slightly softer grade of wheel be used to prevent loading the wheel. A copious flow of lubricant should be used. Where high permeability is required, final grinding (after annealing) should finish with approximately five cuts progressively decreasing from in ( mm) to in ( mm).
