Geological and geophysical models are essential for developing reliable mine designs mineral processing flowsheets. For resource assessment, planning, processing, a deeper understanding of the orebody's features, geology, mineralogy, variability is required. We investigated gold-bearing Black Reef Formation in West Rand Carletonville goldfields South Africa using approaches that components tran...

in theoretical chemistry, molecular structure descriptors are used to compute properties of chemical compounds. among them wiener, szeged and detour indices play significant roles in anticipating chemical phenomena. in the present paper, we study these topological indices with respect to their difference number.

The Ascutita porphyry Cu-Mo prospect is located in the SW Poiana Rusca Mountains, Romania. Current assessment estimates a resource of 110 Mt @ 0.15 % Cu-equivalent. In relatively low-grade deposits such as this, by-products Ag (2–3 ppm) are important determining economic feasibility overall orebody. Assayed Cu and have clear downhole correlation. absence other silver-bearing minerals, or correl...

in this paper, the degree distance and the gutman index of the corona product of two graphs are determined. using the results obtained, the exact degree distance and gutman index of certain classes of graphs are computed.
