What are the 4 processes used in finding new ore deposits?
The steps are: 1) Recognition of geological structure, lithology, stratigraphy, and geological evolution of the region. It is usually summarized on the geological (lithostratigraphical) maps1:100.000, geological cross sections with a real depth, and explanations.
What are some of the tools used to discover mineral deposits?
A geologist’s hammer, rock hammer, rock pick, or geological pick is a hammer used for splitting and breaking rocks. In field geology, they are used to obtain a fresh surface of a rock to determine its composition, nature, mineralogy, history, and field estimate of rock strength.
What is the modern way to locate mineral deposits?
The mineral extraction process begins with finding the location of mineral deposits. Remote sensors that use satellite images and geochemical surveys are just two ways that minerals can be located. Many minerals are then removed through mining or quarrying.
What are the types of mineral deposits?
From a geological point of view, a simple genetic classification of mineral deposits encompasses four main groups: magmatic, hydrothermal, sedimentary, and metamorphic/metamorphosed, each of them with several types and subtypes.
What are different methods of mining?
There are four main methods of mining: underground, surface, placer and in-situ.
Which is the best way to extract minerals from the ground?
The primary methods used to extract minerals from the ground are: 1 Underground mining 2 Surface (open pit) mining 3 Placer mining
How are geologists used to find mineral resources?
Now most mineral exploration is performed by specialized teams of geologists using modern geophysical techniques, including magnetic and gravity surveys, which we will look at in greater detail later in this lesson.
How are mineral deposits found in the past?
In the past, mineral deposits were found by geologists mapping the surface of the Earth looking for clues of valuable mineralization. However, because we have been searching for these deposits for hundreds of years, traditional prospecting methods are rarely used, except in some remote locations such as Alaska and Russia.
What’s the difference between mineral exploration and mining?
Mineral exploration is the process of finding ores (commercially viable concentrations of minerals) to mine. Mineral exploration is a much more intensive, organized and professional form of mineral prospecting and, though it frequently uses the services of prospecting, the process of mineral exploration on the whole is much more involved.
