As with other types of hard rock mining, there are several extraction methods. In the case of uranium mining, it strongly depends on the concentration of uranium in the ore. For example, the ore extracted from the Australian Olympic Dam Mine has a concentration of 0.05 %, and most reserves have uranium with a concentration of between 0.1 bis 0.2 %.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other …
Sublevel stoping is the most popular and practiced mining method in underground hard rock mines. Proper planning and its execution is the key requirement for stope extraction using this method.

The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. What is underground mining? The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining.
The stability of slopes in open-pit mining operations and quarries is extremely important from both economic and safety points of view. The stability of rock slopes entails the design of safe, economical, and functional excavated slopes …
In-pit crushing and conveying (IPCC) systems have drawn attention to the modern mining industry due to the numerous benefits than conventional truck-and-shovel systems. However, the implementation of the IPCC system can reduce mining flexibility and introduce additional mining sequence requirements. This paper investigates the long-term production …
The Definitive Feasibility Study (DFS) described a long life, large-scale, hard rock open pit lithium mine in Mali, West Africa. The DFS Update confirmed that the project is one of the world's best hard rock lithium assets, in terms of scale and cost of production when compared to current operations and prospective projects.
Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. To create an open-pit mine, the miners must determine the location of the ore. This is done through drilling of probe …
The results display that the model can handle the quality and quantity of material required to achieve the objectives of the short-term production schedule of the mine in all CLs, even in the highest risk level. This model has a remarkable ability to meet the required objectives in terms of uncertainty in mining operations.
During the last years BOLIDEN increased production of Aitik mine up to 36 million tons of ore per year. The fast development of the pit in area and depth also leads to an increase of the …
The mine uses conventional open-pit hard rock mining methods (drilling, blasting, loading and hauling) to move copper-bearing sulphide ore to the primary crusher. The processing plant is a conventional porphyry copper concentrator that produces a primary copper sulphide concentrate and a by-product molybdenum concentrate.
Drilling represents the initial and most crucial phase in open pit mining operations that utilize the drilling and blasting method. The mobility of all drilling machineries, facilitated …
EXTRACTION; REHABILITATION; TYPICAL OPEN CUT GRADES; REFLECTION QUESTIONS; Contributors and Attributions; Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the …
In open-pit mining operations, a larger energy consumption comprises the comminution processes. Therefore, blasting operations for rock fragmentation contribute to improving comminution efficiency, particularly in …

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
