Spatial variation and chemical reactivity of dusts from open-pit
Open pit mining of shallow deposits and upgrading of bitumen on a commercial scale began in 1967 (Gosselin et al., 2010). Early work on atmospheric deposition of TEs in the region using snowpack samples focused on V as this is the most abundant metal in bitumen (Barrie and Kovalick, 1980).
Bitumen Mining and Processing in Nigeria; The Feasibility …
To extract the bitumen in the oil sands, conventional oil drilling techniques cannot be used because bitumen is too heavy to be pumped and sticks to sand grains. Therefore other extraction techniques have been developed. The most common methods to extract bitumen are open-pit mining and in-situ, which is Latin for 'in place'.
An optimization model for the real-time truck dispatching
This work is concerned with the real-time truck dispatching problem in open-pit mining operations. The proposed methodology is built on a multi-stage dispatching approach to optimize the truck-shovel material handling systems. The procedure consists of two main stages: allocation planning and dynamic allocation. At first, a scenario-based …
The impact of oil sands on the environment and health
There are two primary extraction methods for oil sands: open-pit mining and in-situ mining. The technique used depends on the depth of the deposit. For example, in-situ mining is used when bitumen lies too deep beneath the surface for open-pit mining. Injection of steam is used in both methods to heat the bitumen, which serves to make it …

Oil Sands Processes
Open Pit Mining. After identifying the potential source of bitumen, the area is cleaned and overburden is removed to ensure the smooth and continuous recovery of oil sands. Once the land is cleaned, it is ready to mine. The first step is to collect the oil sands ore from the ground and transport it to a crushing facility.
Open-Pit Mining Methods
Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the ...
