Limonite has been used by people since prehistoric times. Their first use of limonite was probably as a pigment. It is found in many Neolithic pictographs, and throughout history it has been one of the most important pigments for creating paints in the yellow to brown color range known as ocher. Its use as a pigment continues today.
Limonite ore is a widely occurring iron ore resource characterized by its high content of iron oxide and variable mineral composition. ... Xinhai provides ore processing plant and full set ...
In China, the limonite ore resources total nearly 1.23 Bt, and most of them have not been exploited owing to the limitations of processing technology. Therefore, exploiting refractory limonite ore resources and producing iron concentrate is significant for the iron and steel industry. Download : Download high-res image (280KB)
The gravity beneficiation process uses AM30 jig and 2LTC-6109/8T trapezoidal jig. The AM30 jig machine is used to process large particles of weak magnetic iron ore of 8-30mm, and the 2LTC-6108/8T jig machine is used to process small particles of weak magnetic iron ore of 0-8mm.
For low-grade, fine-grained limonite ore, fine grinding is necessary to help obtain higher-grade iron ore; but at the same time, sludge will occur, resulting in a lower recovery rate. In this case, flocculation-strong magnetic separation can be used. Limonite processing plant in Mongolia
The disseminated grain size of the fine-grained weakly magnetic iron ore is 0.2~0.030mm, and the disseminated grain size of the micro fine-grained weakly magnetic iron ore is generally below 0.030mm. Fine-grained and super fine-grained weakly magnetic iron ore is generally considered to be difficult to process iron ore.
Limonite ore loses free water and crystalline water when heated, and is reduced to magnetite, with an iron grade of 54.15% after roasting. The advantages of magnetization roasting: Removes the crystalline water from limonite ore, improving the iron grade. Reduces limonite ore to magnetite, which is beneficial for subsequent …
The annualized plant results demonstrated that an iron ore concentrate containing 68.4% Fe could be produced using the flow sheet from run-of-mine ore containing 29.1% Fe, at a mass yield to the iron concentrate of 34.8%, an iron recovery of 81.7%, and a tailings grade of 8.2% Fe. ... Most iron ore processing in the fine particle …
