surface course or used as a seal coat in surface dressing. Bitumen emulsion: Bitumen emulsion is a two-phase system consisting of bitumen, water and one or more additives which assist in its formation, stabilization and in modifying its properties. The bitumen is dispersed throughout the water phase in the form of discrete. Surface mining is a technique used to obtain bitumen from oil sands where the oil sands deposits are located fairly close to the surface. If the reserves are shallow enough, earth moving equipment can dig out oil sand for processing. These deposits must be within 75 meters of the surface to be mined in this fashion. Resources recoverable by this type of extraction are .

Ondo, Edo states in the Southwestern and South- southern Nigeria respectively. Tar sand is composed mainly - of heavy oil and clays that are rich in mineral and water. This heavy oil content of tar Sand is commonly called bitumen. In the raw state tar sand is strictly a black viscous substance. The total reserve of heavy oil is. Oil sands must be mined or recovered In situ. The recovery process includes extraction and separation systems to remove the bitumen from the sand and water. The oil sand history started with the development of oil sand separation in the s by Dr. Karl Clark and in Max Ball developed a way to produce diesel oil from oil sand (Nate, ).

To fundamentally understand the electrokinetic behavior of clay minerals, it is necessary to study the anisotropic surface charge properties of clay surfaces. In this study, two layer natural minerals, talc and muscovite, were chosen as representatives of magnesium and aluminum phyllosilicate minerals, respectively. The molecularly smooth basal planes of both platy minerals were obtained. from different ore grades (i.e., low, medium, and high grade oil sands ores).[2,7,8] Although the role of various minerals in the oil sands in water-based extraction has been identified, there is insufficient information about the surface properties of various minerals, especially nano and microsize minerals (NMM), during non-.

Oil sands deposits can actually be found all over the world, including Kazakhstan, Russia, Madagascar and the United States. Although all oil sands contain heavy, complex hydrocarbons, their physical properties can vary. The Athabasca oil sands found in Alberta are water-wet, meaning a layer of water is thought to coat the bitumen and solids.

In a 1 mM KCl solution, the effect of pH on the interaction force between the bitumen and a silica particle is shown in Fig.

Oil sands are a combination of clay, sand, water, and bitumen.The bitumen is similar to crude oil but denser with higher viscosity, averaging % carbon, % hydrogen, % oxygen, % nitrogen, and % water extraction process (HWEP) is a mining, ex situ method currently employed in Canada for extraction of bitumen.

sands. This is due to its influence on nearly all the properties of oil sands among which includes viscosity, surface tension and bitumen-solids adhesion that impose prominent impact on bitumen recovery [9]. Sodium hydroxide (NaOH) is known to have strong pH-regulating capability and is mostly used for alkalinity.

Oil sands slurry contains bitumen, water, fine solids, coarse sand and the occasional rock or oversized debris. Heavier objects will take different trajectories than the finer solids.

If the coarse sand and rocks are not evenly distributed, they will strike the wall of the vessel at exactly the same location, eventually wearing a hole in the.

Abstract. Mathematical modeling of ultrasonic or mechanical separation of oil sand in an aqueous alkaline medium was performed. Kinetic dependences were obtained that adequately describe bitumen recovery based on the limiting role.

The section on mechanical properties introduces the concepts of time-temperature-age dependency of asphalt binders as well as typical methods and models used to measure these properties.

Water-based bitumen extraction technology from mineable oil sands faces major challenges of high water usage and tailings disposal. In the present study, a process for solvent extraction of. An oil sand sample was obtained from Alberta (Canada).

Solvent extraction was performed based on a previously established protocol for bitumen from oil sand [11]. Briefly, a solvent/oil sand. About 80% of Alberta's bitumen reserves are too deep to be mined and must be extracted in-place (or in-situ) using n is heated and pumped out of the ground, leaving most of the solids behind.

In-situ extraction has a much smaller footprint than oil sands mining, uses less water, and does not produce a tailings stream. oil sand near the surface (bitumen as a fuel source to generate energy, it must be first extracted from oil sand and then collected.

The main industrial processes used to extract bitumen from oil sand include treatment with hot water ( C) and steam (> C) in rotating drums.5) The bitumen content of oil sand is 10– 15wt%.

At present, the methods for separation of bitumen from oil sands involve hot water extraction[1], [2]solvent extraction, and retorting[3].

The hot water extraction process is the only commerciallized process for recovering bitumen from oil sands. In the process of separating bitumen from oil sands by hot water extraction, it is necessary to add an. A method of separating oil and bitumen from sand.

Firstly, mixing sand containing oil and bitumen with water in a tank to form an aqueous slurry. Secondly, adding a water solution of hydrogen peroxide to the aqueous slurry and agitating the aqueous slurry.

The hydrogen peroxide serves as a catalyst initiating a vigorous reaction that separates the aqueous slurry into an. In the paper physical and chemical properties of natural bitumen of oil sands were investigated. For the determination of organic part (natural bitumen) of oil sands the extraction methods was used in Soxhlet apparatus by solvent.

Physical and mechanical characteristics of natural bitumen (NB) are established by standard methods: softening temperature was determined by.

1. Introduction. The history of oil sand or tar sand started with the development of oil sand separation in the s by Clark and the rise of crude oil prices, investment in oil sand production tripled over the years and has become a booming business (Suncor Inc.

).Miller et al. () have studied the separation of bitumen from American oil sand. Also oil sand-diluent conditioning time is an important process parameter and can vary from a few minutes for oil sands with low-viscosity bitumen to several hours if viscosity of the bitumen.

Asphalt binder comprises four main fractions—asphaltenes (A), saturates (S), aromatics (A), and resins (R)—referred to as “SARA”. Asphaltenes plays an important role in determining the linear viscoelastic behavior of asphalt binders.

In this research, asphaltenes are added as a distinct modifier to improve the performance properties of asphalt binder. The different properties of various oil sands ores can be described as an average combination of the properties of these four end members.

2, 5 Each petrologic type can behave diversely during a bitumen extraction process (either aqueous or non‐aqueous), due to the different mineralogical and chemical compositions.

Petroleum products are produced from the oil sands through 3 basic steps: Extraction of the bitumen from the oil sands, where the solids and water are removed.; Upgrading of the heavy bitumen to a lighter, intermediate crude oil product.; Refining of the crude oil into final products such as gasoline, lubricants and diluents.; Traditionally, a majority of the bitumen .
