Overall the beneficiation of black shale is difficult and complex; still, processing the latter needs pretreatment such as pyrometallurgy requiring froth flotation. In Egypt, organic-rich sediments in the Duwi and Dakhla Formations of the Campanian-Danian age are customarily assigned as “oil shale” that occupies the middle latitudes of the country but may extend southward to Kurkur Oases. This oil shale belt has a vast worldwide extension, and it is considered as major oil- and gas-prone source rock in Oil shale resources in Egypt: the present status and future vision

The elevated attention in respect to mineral processing in the past couple of decades has principally been focused on four black shale deposits: (i) Kupferschiefer Cu-Ag ore (Poland and Germany) (Borg et al., 2012), (ii) Ni-Mo-PGE polymetallic ore in Guizhou province and its extension in other districts (China) (T. Han et al., 2014), and (iii) Abstract Improving the organic content in oil shale before retorting is a substantial target. The flotation process is proven as a good separation process for hydrophobic particles from their associated impurities. In this study, the natural floatability and the flotation with different types of reagents were investigated to show how effective Effect of chemical additives on oil shale natural floatability

Significant variability in ore grades and mineralogical characteristics impose challenges during selection of a proper beneficiation process to upgrade the low-grade manganese ores. In the present review paper, an attempt has been made to summarize the various kinds of beneficiation practices used to upgrade the low-grade Feldspar is a valuable raw material in the manufacture of glass, ceramic, fillers, enamel frits, and welding electrodes. Feldspar is the single most abundant mineral in the earth crust and is generally associated with other silicate, titanium, and iron minerals. As a result, beneficiation of feldspar is necessary to obtain high-grade materialsSystematic review of feldspar beneficiation and its comprehensive

Oil shale beneficiation by froth flotation hasn't received enough attention in the last two decades. The reason was the economics of the process as well as its environmental impact.The application of new beneficiation and smelting technology has improved the grade of concentrate beneficiation. This article discusses the commonly used six different gold beneficiation methods and The technical process is compared and introduced. According to different types of gold ore, different gold extraction techniques are adopted.Six kinds of beneficiation methods,beneficiation process

Methods for liberating organic carbonaceous products from mineral matrices such as oil shale and the products liberated by the present methods inter alia, the invention in a preferred embodiment subjects oil shale to resonance disintegration including inter alia rapid pressure and directional changes to essentially instantaneously vary forces acting thereon.Oil shale of 0–50 mm can be effectively separated by the new dry beneficiation process. Abstract. Oil shale is considered to be the optimal alternative energy sources due to its large reserves and high oil content. However, it is accompanied by large quantities of inorganic mineral impurities in the mining and should be beneficiated firstlyStudy on the effect of autogenous medium characteristics on oil shale

Clearly, the latter is the more relevant to an ore beneficiation process. The result obtained with this material is less favorable than that achieved with the Marathon cores. Still the increase in kerogen content from a value of 21% for the raw material to 62% for the upgraded pellets represents a rejection of 83% of the mineral matterflotation, and dewatering).
