چکیده
There are two kinds of chlorites occurred in Anshan area, among which the hydrothermal Fe-chlorite with longer Fe-OH wavelength is spatially related to high-grade magnetite ore, meaning that mapping can be used target BIF-hosted high grade iron ore. In this article, quadratic polynomial, cubic spline, and quartic polynomial method were interpolate absorption near 2250 nm China ZY1-02D satellite hyperspectral image. The result continuous without data overlapping or intervals, thus most suitable for discrimination chlorites. field truth shows spatial distribution Fe-chlorite, validated by XRD analysis, not only accordance ore bodies, but also consistent recently discovered concealed bonanza. study remote sensing techniques play significant role exploration east Liaoning Province.

Analyzing the effect of ore grade uncertainty in open pit mine planning; A case study of Rezvan iron mine, Iran
Due to uncertain nature of grade in ore deposits, considering uncertainty is inevitable in geological modelling of resources and mine planning. In other words, uncertainty in grade of mineralized materials, is one of the most significant parameters need attention in mine planning. In this paper, a comparative procedure utilizing Sequential Gaussian Simulation (SGS) and traditional Ordinary Krig...
متن کاملDetermination of Ore/Waste Boundary Using Indicator Kriging, Case Study: Choghart Iron Mine of Iran
Estimation of ore reserves is one of the most critical aspects of mining geology. The accurate assessment of the tonnage and grade of run of mine may be the difference between a healthy profitable operation and an expensive early mine closure. The first step in ore reserve estimation is to determine the boundary of ore body or ore/waste contacts. This paper presents a specific mining applicatio...
متن کاملCharacterization of Sangan low-grade iron ore and its processing by dry low-intensity magnetic separation
In Sangan iron mine nearly two million tons of low-grade iron ore has been extracted and deposited in the mining site and currently no action is made on them. On the other hand, the mining site is located in the semi-arid region and wet processing has been restricted due to water shortage. In this research, the upgradation of Sangan low-grade iron ore from mine B has been performed by dry low-i...
متن کاملHigh-rate behaviour of iron ore pellet
Iron ore pellets are sintered, centimetre-sized spheres of ore with high iron content. Together with carbonized coal, iron ore pellets are used in the production of steel. In the transportation from the pelletizing plants to the customers, the iron ore pellets are exposed to different loading situations, resulting in degradation of strength and in some cases fragmentation. For future reliable n...
