If chromite minerals occurs in fine grains intermixed with host rock, crushing, gravity separation and magnetic separation may be used. Lumpy ore mixed with host rock may require heavy medium separation. Coarse clean ore is hand sorted, while the fine clean ore is gravity separated.Chromite ore is beneficiated for processing using several methods, depending on the ore source and the end use requirements.
if the lubrication oil is too thin, it would cause the metal friction with each other directly , so lead the bearing temperature rising up,. And lubricating oil fluidity is very poor, cannot take heat away in time, and so would lead the temperature of bearing rising up. If the lubrication oil too thick, it not only increased the internal friction between the oil molecules, but also increases the friction between the oil and metal, so that would produce much heat.Too thick or too thin of lubricating oil can lead to bearing temperature rising too high.
Vertical roller mill directly decides the fineness and quality of final coal powder. It is not only because that the specifications of LM130M vertical coal grinding mill are suitable for the customer, but also there are some other features and advantages of this mill making it particularly suitable for Mongolia coal grinding.
The reefoidal limestone is the dominant deposit in the Jeddah area. Above these limestone deposits is a surficial soil layer which consists mainly of aeolian sands and gravels that were deposited in Holocene times. All the available boreholes indicate the presence of coastal coralline limestone (coral reef deposits) which contain fresh shells and are typically cavernous in nature.
The relative contents of elements are given in Table 2.It was inferred that DDA mainly interacts with Na, K and Al on the feldspar surface at pH 2 by ATR-FTIR analysis. According to the obtained results, the relative content of feldspar before HF pretreatment is mainly O, Al, Si, K and Na atoms. The binding energy of elements on the mineral surfaces untreated and pretreated by 2000 g/t HF with 5 × 10−4 M DDA at pH 2 are listed in Table 1. The main peaks include: Al(2p) located at ~75 eV, Si(2p) at ~103 eV, C(1s) at ~285 eV, K(2p) at ~300 eV, O(1s) at ~531 eV, and Na(1s) at ~1072 eV [31,32,33]. To provide straightforward evidence of this, XPS measurements of feldspar and quartz were carried out, and are shown in Figure 9 (full spectrum scanning). In addition to the elements belonging to the mineral or the reagent, the presence of carbon, the so-called adventitious carbon, was observed on the minerals surface.
