Development of Argyle was a two-stage process. Alluvial diamond mining took place between 1983 and 1985, when the AK1 pipe came into production. Since then, this has been the principal source of ore, supported by lesser amounts of alluvial material.
Diamond is a solid form of pure carbon with its atoms arranged in a crystal. Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common allotropes of pure carbon are diamond and graphite.In graphite the bonds are sp 2 orbital hybrids and the atoms form in planes with each bound to three nearest neighbors 120 degrees apart.
Alluvial diamond-bearing gravels commonly yield diamonds that are predominantly of gem quality. ... In the processing plant, the diamond-bearing ore is crushed and passed as slurry through various stages of separation and screening to form a concentrate. Diamonds
munity as a method for independent verification of alluvial diamond resources. A similar assessment was also conducted by the U.S. Geological Survey (USGS) in Liberia (Wahl and others, 2007). The USGS assessment made substantial contributions to the assessment process of the diamond potential and contributed to a lifting of the sanctions on
