The accessible ore of oil sands is located 50 to 200 m from the surface. Due to the difference in depth, recovery of oil sands ore calls for different techniques: open pit mining for shallow resources and steam assisted gravity drainage (SAGD) for deeper resources. These two oil sands processes techniques are described in more detail below.

When do issues of complexity outweigh the practicality of experience-based judgement? Prior to the arrival of computer-generated flow models, heurism and the application of simple, practical, tried-and-proven techniques resonated at the heart of any mining operation. With the current reliance on overly designed and time-intensive numerical models, are we …

Open Pit Mining Awwad H. Altiti, Rami O. Alrawashdeh and Hani M. Alnawafleh Abstract Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high produc-
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, …

Haulage costs as the main part of oil sands truck-and-shovel operations costs contribute for over 50% of open pit mining costs [1,2,3,4], which shows the importance of haulage system efficiency in overall profitability of open pit mining operations.Determining the right size of the haulage fleet will optimize the overall fleet utilization and hence, improves the efficiency.
Material handling in open pit mining accounts for about 50% of production costs. The selection and deployment of efficient, safe, and economic loading and haulage systems is thus critical to the production process. ... using these models the truck flow rates and the number of truck trips were determined. In order to implement these models, the ...

Mined sulfur is mostly from salt domes or bedded deposits. The vast majority is produced as a by-product of oil refining and natural gas processing. Sulfur mining uses three different mining techniques: conventional underground methods, conventional open-pit methods, and the Frasch mining (or underground melting) method.
