The source of ore metals

01.07.1971Whatever the agent may be, it seems widely agreed that sedimentary processes by themselves, acting on ordinary materials under ordinary circumstances, do not form ore deposits of heavy metals, but may do so if the metals have undergone previous enrichment in the materials being furnished to the sedimentary agents.

9 Ore Deposits and Economic Minerals – Mineralogy

The concentration of a commodity in the ore (the "richness" of the ore) determines the ore grade. When calculating the profitability, amount of reserves and ore grade are the most significant geological factors, although economic factors such as extraction costs, processing costs, and market price are often more decisive.

In this study we delineate the subsurface structures within an area of about 145 000 kmSUP2/SUP in the Central Eastern Desert of Egypt (CED), using magnetic methods. The main goal is to establish the tectonic framework of the study area and to understand the role of tectonics in the mineralization process. Aeromagnetic data covering the study

Mine reclamation

Reclamation processes. As part of the life cycle of a surface coal mine, completed mine areas must undergo rehabilitation.When mining ends, operators must restore the land to its approximate original contour (AOC) or leave the land graded and suitable for a "higher and better" post-mining land use (PMLU) that has been approved as part of the original mining permit application.

Iron ore

The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting.

The paper extends to three dimensions (3-D) the two‐dimensional (2-D) Hilbert transform relations between potential field components. For the 3-D case, it is shown that the Hilbert transform is composed of two parts, with one part acting on the X component and one part on the Y component. As for the previously developed 2-D case, it is shown that in 3-D
