Aug 30, 2017 Separation of Heavy Mineral Concentrates Moclips Beach Sample. The processing sequence for the recovery of gold, ilmenite, and zircon from the Moclips Beach sample is shown in figure 2. This sample contained more ilmenite and zircon per ton of sand than any of the other samples obtained from the sand and gravel plants
Step 2. Cut various grades of steel mesh to fit each box. Use the widest opening in the steel mesh of about 3/4 inch to sift out the larger gravel stones. Half-inch steel mesh will give you a smaller grade of gravel while 1/4-inch screen separates the smaller particles of stone. Build a final screen with 1/8-inch mesh if you want fine sand

Each letter is described below (with the exception of Pt):
Furthermore, to avoid sieving errors, the results suggest that the dry-separation method should not be used for silt-sand-gravel soils exceeding 2% silt size fractions. The dry-separation method is an alternative to the wet-preparation in the current European Standard for the determination of particle size distributions by the sieving of soils
