Nanostructured IrO
A two-electrode cell driving overall water splitting was assembled by employing IrO x /N–TiO 2, IrO x and IrO 2 (CM) as the anode catalysts, Pt/C(CM) as the cathode catalyst. Polarization curves are shown in Fig. 4a, the IrO x /N–TiO 2 ||Pt/C(CM)-based cell performs the lowest voltage of 1.785 V to deliver 100 mA cm −2, meaning the ...

An operational model for a spiral classifier
1. Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).The development …

Effect of wash water on the mineral size recovery curves in a spiral
The spiral used for the tests is a 7 turn WW-6E from Roche Mining. The set-up used for the experiments is shown in Fig. 1.The feed material is a ground ore from the Mount Wright Arcelor-Mittal mine in Quebec (Hyma and Meech, 1989).The ore is mixed with water and the slurry is loaded into pump box A (see Fig. 1).The slurry is pumped to a …

5 Ways to Remove Iron From Well Water (Easy Methods)
Reverse osmosis is the cheapest way to remove iron from well water. A good RO system can cost you between $200 – $500, and can remove upwards of 90% of the iron in the water, which makes it significantly cheaper than other iron treatment methods. The system's size and cost will depend on the amount of iron you have in your well system …

Dense Media Separation (DMS) Plants
Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

A washing section is a "must" in all operations handling wet, sticky ore. This facilitates ore handling, crushing, and also affords a means for separation of primary slimes and increasing grinding capacity. These slimes usually contain the bulk of the soluble salts and in many cases this fraction should be treated separately or even ...
