Size Grade Mineralogy of Mineral Sands Deposits The size grade of strandline deposits varies greatly – on average a strandline deposit would be 100-150m wide and approximately 2- 20km long HM grades may vary from approximately 2% - 90% HM with the strandline itself Offshore deposits typically have different mineralogy to strandline deposits the VHM is finer grained usually Zircon rich

Ore geology Ore deposits are delineated by mineral exploration which uses geochemical prospecting drilling and resource estimation via geostatistics to quantify economic ore bodies The ultimate aim of this process is mining
Placer deposits are accumulations of heavy minerals formed by gravity separation during sedimentary transport Placer deposits in South Africa and Namibia due to the erosion of kimberlites on the Kalahari Craton in South Africa
The Occurences of Heavy Mineral Placer at Kendawangan and Its Surrounding West Kalimantan Province The main objective of this study is to identify and to determine the variation and content of heavy mineral placer of Kendawangan coastal offshore and its surrounding area
Mineral deposits refer to occurrence of one or more minerals in concentration to constitute a deposit of economic value An ore refers to a mineral aggregate from which one or more metals can be profitably extracted A mineral deposit generally consist of one or more metallic ferrous minerals associated with unwanted or wasteful mineral or rock matter known as gangue
Due to the low quality of the ilmenite the economic value of Liberia's heavy mineral sands is therefore confined predominantly to the rutile and zircon Current reserves of these two minerals are only 99 380 tons of zircon and 84 070 tons rutile
