A mineral reserve is a portion of a mineral resource that has been demonstrated to be economically and legally extractable under current socio-economic and operating conditions.
Lithium minerals are naturally occurring compounds that contain economically significant concentrations lithium in various forms, including lithium carbonate, lithium hydroxide, and lithium chloride. The most common lithium minerals include: Lithium Minerals It has been studied those concentrations exceeding 0.5% are feasible to extract lithium. Lithium deposits Lithium deposits are natural concentrations of lithium in rocks, … Read more
Ore Reserves are part of mineral resource that are economically feasible for extraction using current technology. For ore reserve the grade and tonnage should be established with reasonable assurance by drilling & other means.
Ore is aggregate of minerals and that can be can be economically extracted from the rock. Examples : Galena (Lead Ore) Ore Deposit An ore deposit is an accumulation of a particular ore or more than one ore. Most ore deposits are named according to their location (for example, Tummalapalle Uranium Deposit, India), or after a … Read more
The development of geostatistics as an ore reserve estimation methodology emerged in France in early 1960 from the work of Matheron (1962) and was based on original studies by D.G. Krige functioning the optimal assigning of weights to the neighbouring sample values used in estimating the grade of blocks in South African gold mines. Geostatistics … Read more
INTRODUCTION In areas where soil cover is thin, the location and testing of bedrock mineralisation is made relatively straightforward by the examination and sampling of outcrops. However in locations of thick soil cover such testing may involve a deep sampling program by pitting, trenching, or drilling. Pits and trenches can be a quick and cheap … Read more
Lithologging of drill core of boreholes is an important stage in mineral exploration and it is done in reconnoitery, exploratory and evaluation stages of drilling to characterise the lithology. What is lithologging? Lithologging is systematic, depth wise enumeration of details of Core/Sludge samples or rock exposure in cross sections. Objective of lithologging: The basic objective … Read more
