Effect of acid concentration on the leaching of magnesite for 30 and ...

The aim of the study is to examine the reaction of calcined magnesite in the citric acid media, and after that it is determination of optimal conditions about the leaching performance of calcined ...

Leaching of Magnesite and Dolomite by Hydrochloric Acid

The primary objective of this thesis was to determine the optimum process parameters for the leaching of magnesium carbonate. The ore used for the experiments was a cryptocrystalline magnesite ore from a 516 million tonne magnesite resource located North West of Leigh Creek in South Australia. Thiess Pty Ltd is currently designing a plant to process this ore. The first stage in the process is ...

MagnesiumGeoscience Australia

There are two main uses for magnesite magnesium carbonate. The first is in the production of dead burned magnesia for refractory brick use. These bricks are physically and chemically stable in high temperatures and are used to line furnaces in the steel industry, non ferrous metal processing units and cement kilns.

Magnesium recovery from magnesite tailings by acid leaching and ...

The leachingics fit thedo second order reaction model. The activation energy of the reaction is 62.4 kJ mol 1. About 92 of the magnesium in the magnesite tailings could be recovered at a temperature of 40 °C, 1.0 M acid, solid to liquid ratio of 10 g/L, particle size of 100 µm, stirring speed of 1250 rpm and leaching time of 60 min.

US5112584A Method for production of magnesium chloride Google

A two stage leaching process is used where in a first reactor magnesite lumps are dissolved in hydrochloric acid. The magnesium chloride containing solution is led to a second reactor, where...

Leaching of natural magnesite ore in succinic acid solutions

The impact of succinic acid solution strength and liquid to solid proportion on leaching rate of magnesite was determined. The experimental results are presented in Fig. 4, Fig. 5 respectively. From Fig. 4, it can be observed that an increase in acid concentration from 4 to 7 increases conversion of magnesite ore from 47.7 to 88 in 40 min of reaction.

Magnesite SydneyInfo About Magnesite In Australia

Magnesite was mainly used in Sydney, as a slab topping or an underlay to carpet and other forms of floor covering. Magnesite is extremely rich in chlorides, resulting in problems of sweating, diffusion of chloride ions into the concrete substrate and metal corrosion, usually seen as lumps appearing below the carpet or cracks in the floor tiles.

Leachingics of Calcined Magnesite in Citric Acid Solutions

Theics of leaching of calcined magnesite by citric acid solution was studied. The effects of reaction temperature, particle size, and acid concentration were investigated. The leaching data showed that the reaction is under chemicalics control with an activation energy of 39.1 kJ mol 1. Additionally, the fact that leaching was controlled by the chemical reaction was also supported ...
