Accordingly, the claimed process shall not be restricted to any specific gold processing operations provided that, in some manner, cyanide solutions are used to chemically extract gold from mined ore so that a gold-cyanide complex is created. While specific processing systems and gold recovery technologies will be discussed in connection with the claimed procedure, the present invention shall not be limited to any particular cyanide-based gold extraction methods. Instead, the invention is prospectively applicable to any production system which places gold ore in physical contact with solutions containing free cyanide ions(CN)- ! therein so that a gold-cyanide complex as defined above is generated.The claimed process overcomes the problems outlined above in a very effective manner which will become readily apparent from the detailed information presented below.

7 billion) railway project contracted by China Communications Construction is the largest project conducted by Chinese companies overseas at present and also one of the most prominent ones under the Belt and Road initiative.Aug 9: The ground-breaking ceremony for Malaysia's East Coast Rail Link was held in Kuantan, the capital of Pahang.

The measure of the standard deviation of the features (quarries) from the mean center, major axis extending in the northwest–southeast direction and minor axis in the southwest–northeast direction, is the consequence of geological settings. The change in the shape of the weighted production ellipses (2010 and 2018) and different shape of the ellipses for the unweighted and weighted data also point to the slight eastward shift of production and concentration (smaller x and y axes of the 2018 ellipse compared to the 2010 ellipse) of rock raw material production.
80 and 0.84, and Mg# ratios between 0.82 and an Mg# ratio of 0. Massive chromite pods, with an average Cr# ratio of 0. They are all irregular in shape and mottled, showing inhomogeneity of composition. They are high in Cr and high in Al, often in a spatial association, hosted within completely serpentinized, weathered, and intensively deformed dunite–harzburgite blocks, due to a strong plastic and brittle deformation, which had an important influence on their present form and distribution . At Milia, the PGMs are predominantly Os, Ir, and Ru iridium/PGE (IPGE) alloys and sulfarsenides, rather than laurite, and are all less than 5 μm in size (usually less than 2 μm), while heazlewoodite and awaruite occur in the serpentinized matrix .72 contain relatively low (≤170 ppb) PGE content .The chromitite occurrences in the Pindos ophiolite complex are small (a few tens of meters × a few tens of centimeters) and are of all textural types (massive, schlieren, banded, disseminated, and nodular). They are mainly Os–Ir–Ru–Rh (±Ni) alloys with minor Pt, altered occasionally to oxides [38,39].40, exhibited elevated PGE content (up to 1060 ppb ΣPGE) (Table 1) , while other chromitite occurrences at the Milia area having Cr# ratios ranging between 0.54 and 0.
