Sui Ility Of An Ore Deposit For Economic Mining And Processing

Dec 12, 2019 Nick, We can agree that, by definition, mineral resources must have reasonable prospects for eventual economic extraction. Where a PEA Technical Report differs from a mineral resource statement, though, is that it requires additional sections that set out the expectations of the project proponent as to: the potential mining and processing methods; the scale of operation; labour

    ORE DEPOSIT TYPES AND THEIR PRIMARY

    PRIMARY EXPRESSIONS OF ORE DEPOSITS A well known aspect of ore deposit expression is the association of particular ore types with particular host rock assemblages, i.e., the ore-host rock association (e.g., Stanton, 1972). This association broadly reflects the geological environment and processes that have formed the ore

    Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade. Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open-pit mine methods (Figure 20.1). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less

    Prospecting and exploration are precursors to mining and often occur simultaneously; together, they can take two to eight years to complete, and may cost from $500,000 to $15 million overall. Prospecting is the process of searching the region for mineral deposits. Historically, prospectors would explore a region on foot with a pick and shovel

    An ore deposit may be either of igneous or of sedimentary origin. Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. Within these three broad modes of origin, a mineral deposit of economic value might have originated due to set of simple or complex processes. Types of Ore Deposits: 1

    Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains

    9.1.3 Mineral Deposits, Ore Deposits, and Mining. A mineral deposit is a place in Earth’s crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true
