Ultra-fine iron tailings mainly comprised SiO 2, Fe 2 O 3 and MgO, followed by CaO and Al 2 O 3 . The sulphur content in the tailings was low and was not majorly involved in the reaction during the filling process. As shown in Figure 9d, the mineral composition of ultra-fine iron tailings was dominated by quartz, mica, talc, dolomite, etc.

FSP experiments were performed on a MTS PDS-4 Intelligent-Stir using a MP159 alloy tool with a scrolled shoulder of 9.5 mm in diameter and a three sided threaded pin slightly shorter than 2 mm in length.A rotation rate of 700 rpm in clockwise direction, a traversing speed of 120 mm/min, and a tool tilt angle of 1.5° were used.In order to …
Literature shows that flotation is highly size dependent and processing both coarse and fine size fractions is problematic. The latter is the subject of the current paper. Fine particles have a relatively high surface area, and therefore more reagents are needed for their processing. In addition, the problem of fine particle flotation is mainly ...
Microstructures of calcite veins provide an excellent opportunity for investigating fracture opening processes in a tectonically active, ultra-deep foreland basin setting. The syntaxial calcite vein is the dominant type and is formed through a single crack-seal event. Calcite crystals in fractures show blocky and elongated blocky shapes.

The net volume of the milling chamber was 0.95 l.The grinding media used were alumina 1 mm balls produced by Nikkato Co., Ltd., Japan, 99.9% pure and density 3.60 g cm −3.The devices used to measure the energy consumption consisted of an automatic voltage regulator, GPA 100SS AVR (Sung Sin Electronic.
The calcination process utilizes the heat value in the residual organic matter which reduces fuel costs and increases the REE content to values approaching the ash-based value in the sorted material. A potential step not shown in Fig. 17 involves the removal of calcite by froth flotation to reduce acid consumption during leaching.

The kinetics of aggregation/breakage of calcite particles flocculated with a high-molecular-weight polymer flocculant has been studied in turbulent pipe flow. The mean flocculation residence time was varied by changing the length of pipe between the flocculant injection point and the in-stream particle-sizing probe (Lasentec FBRM).

Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of …
In all flow-through experiments, a marble (grain size ~50–300 µm) from Berkovica (Bulgaria), containing calcite (composition Ca 0.988(±0.002) Mg 0.009(±0.001) CO 3) and minor quartz and muscovite, was reacted with a solution containing 0.08 M MgCl 2, 0.06 M CaCl 2 ·2H 2 O and 0.28 M NaCl (Baker and Kaster 1981).This particular …
