摘要： An aperature is formed in the bottom wall of the launder. A downwardly extending container communicates with the aperture. A weir is positioned immediately downstream of the aperture. The container and weir combine to form a separator. In the launder, free water and solids contaminants settle and form a bottom layer of dirty water. The layer is diverted into the container through the aperture and the weir temporarily retains a small head of it. Temporary retention in the separator therefore generates a vertical fluid column comprising an upper layer of relatively clean froth and a lower layer of dirty water, said layers having an ascertainable interface. The elevation of the interface is monitored and contaminated fluid is withdrawn from the container as underflow at a rate controlled to keep the interface elevation substantially constant. The froth overflowing the weir is reduced in water and solids relative to the original froth issuing from the flotation vessel.

摘要： Aerated bitumen froth containing bitumen, water, air and solids is the product of the hot water extraction process for recovering bitumen from oil sand. Measurements related to the water content of the froth can be obtained by measuring its resonant frequency in a calibrated output, open-ended microwave cavity. By also measuring the bulk density of the froth and assuming a constant relationship for the solids content, one can compute from the assembled data the output quality of the froth. The measurements can be taken repetitively at the vessel as the froth is produced and used to almost instantly provide froth quality information.
摘要翻译：含有沥青，水，空气和固体的充气沥青泡沫是从油砂中回收沥青的热水提取过程的产物。通过在校准输出，开放式微波腔中测量其谐振频率，可以获得与泡沫水含量相关的测量。通过测量泡沫的体积密度并假设固体含量的恒定关系，可以从组合的数据计算泡沫的输出质量。在产生泡沫时可以在船上重复测量，并且几乎立即提供泡沫质量信息。

摘要： An improvement in the processing of bituminous sands is described, whereby the concentration of bitumen in tar sand feed is measured by infrared light reflected from the tar sand surface. Near infrared is shone onto the surface of the incoming tar sand and reflected light is collected and passed through two parallel filters, one being a measuring filter having a wavelength range of 2180 to 2260 nm and the other being a reference filter having a wavelength range of 2270 to 2350 nm. The beams emerging from the filters are measured electronically and the resulting signals are separately integrated and amplified by electronic means. The ratio of the amplified signals is used to provide a read-out signal responsive to the bitumen concentration. The results may be used to adjust processing conditions in the extraction process to allow for the variations of bitumen in the feed.
摘要翻译：对沥青砂的加工进行了改进，由焦油砂表面反射的红外光测定沥青砂进料中沥青的浓度。近红外线照射到进入的焦油砂的表面上，反射的光被收集并通过两个平行的滤光器，一个是具有2180至2260nm的波长范围的测量滤光器，另一个是具有波长范围为 2270〜2350nm。从滤波器出射的光束被电子测量，并且所得到的信号被单独地集成并通过电子装置放大。放大信号的比例用于提供响应于沥青浓度的读出信号。结果可用于调整萃取过程中的加工条件，以允许进料中沥青的变化。
