Iron ore concentrate sales in a mineral processing plant appeared a trend of high sulfur, exceeding the sales requirement of 0.3% significantly. To this end, for the sulfide in iron concentrate mainly exists in the form of pyrrhotite, companies with iron minerals and has a high degree of oxidation, we can add flotation agent to the magnetic separation column, and at the same time fill gas for s...

The reserve of the copper-oxide-bearing limonite ore (COBL ore) in Yulong Copper Co., Ltd. is up to 20 million tons with 1.79% copper content. characters resources COBL are high-proportioned oxidation state (99.98%) and combined (84.83%). oxide mainly limonite, which has a content more than 78%. Because high altitude average annual temperature 15 °C Tibet, fire leaching cannot be adopted. effic...

According to the publication by US Minerals Survey in 1999, the total reserve of manganese ore in the world is 0.66 billion tons. See Table 1. Table 1 World Manganese ore reserve(Mn metal weight, million tons) __________________________________________ Name of counties Reserve in 1999 __________________________________________ South Africa 370 Ukraine 135 China 40 India 34 Australia 26 Gabon 20...

The plant species Pinus halepensis grows spontaneously on heavily polluted mine tailings dumps of Campo Pisano (Sardinia, southwestern Italy). area is characterized mainly by Zn, Pb, and Cd. Sampling campaign was done, related to soils materials (roots, barks, wood, needles), aimed at evaluating the main mineralogical characteristics, metal content, accumulation, translocation behavior. substra...

The current version of the Tax Code allows for misinterpretation interpretation term "primary processing mineral resources". In particular, tax authorities believe that primary raw materials includes magnetite concentrate, which in this case is subject to taxation. That is, a number mining and enterprises have faced problem double taxation, threatens significant financial losses. Accordingly, l...

In this paper, iron ore sample from the Chadormalu was investigated to determine some comminution properties. Chadormalu deposit is one of the largest iron ore mine in Iran, which is located in Yazd province. The representative ore sample contained 57%Fe, 0.9%P and 0.17%S. The sample was crushed; afterward, it was ground in various grinding times according to the Bond Ball mill approach to spec...

This paper present the results of a preliminary study to assess the potential of the visible, NIR and SWIR energy of the EMR in differing iron ores of different grades in a rapid manner using hyperspectral radiometry. Using different iron ore samples from Noamundi mines, Jharkhand, India, certain spectro-radiometric measurements and geochemical analysis were carried out and the results have bee...

This case study utilizes a value of information decision framework to provide mine managers guidance regarding the purchase of ore grade scanners. LKAB’s Kiruna mine produces three types of iron ore to meet long-term contractual agreements on a monthly basis. There is a priori uncertainty regarding the ore type in any given mineable section of the orebody. In addition, there is extracted ore ty...
