Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, % Fe), hematite (Fe 2 O 3, % Fe), goethite (FeO(OH), % Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
Precipitation of calcite in post ore fractures and cavities and dolomitisation of Waulsortian Limestone. The original resource/reserve has been variously quoted as: Mt % Zn, % Pb, % Cu, 50 g/t Ag, or Mt % Zn, % Pb, % Cu, 31 g/t Ag. The nonsulphide zinc mineralisation is estimated to have totalled:

The analysis of the Ag and Au contents in ore bodies of different formation types reveals that the Ag/Au ratio functionally depends on the relative sulfide index of the ores (the ratio between the product of the Pb, Zn, and Cu content and the gold content). The functional dependence is best approximated by a power function. Based on 85 geochemical characteristics of 29 deposits, it is shown ...

In the article the results of processing oxidized copper polymetal ore and iron ore tailings by heap leaching irrigation and sorption methods have been analyzed. A study was made of conditions for concentrating some nonferrous metals (Cu, Zn, Ag, Au, Co, Mn) by hydrolytic precipitation and sorption methods. As well, it is reported on the results, were obtained, on utilization of arsenic from ...

Fig. 1. Linear regressions between inuse stocks and GDP for Cu (A), Zn (B), Al (C), and Fe (D).The correlations have an R 2 > for copper and aluminium, whereas zinc and iron still retain an R 2 > The small sample sizes, Fe (n = 7), Al (n = 8), and Zn (n = 6), may be of some concern, yet the correlation appears to hold when more studies are available, Cu (n = 18).
