The following optimum leaching parameter levels were found: temperature 50°C, solid-to-liquid ratio 2%, acid concentration 20 g/cm (2 mol/dm), stirring speed 450 rpm, leaching time 5 min. Under the optimum process conditions, the dolomite ore leaching efficiency was about 83%.

Step 1： Dolomite ore is crushed and heated in a kiln to produce a mixture of magnesium and calcium oxides, a process known as calcining: Step 2： The next step is reduction of the magnesium oxide. The reducing agent is ferrosilicon (an alloy of iron and silicon) which is made by heating sand with coke and scraps iron, and typically contains ...

The extraction of magnesium from dolomite ores can be done by leaching process. In this work, the dolomite leaching to extract magnesium by hydrochloric acid was investigated. The leaching experiments were performed in a spherical glass batch reactor having a capacity of 1000 ml.

Let's take a look at the dolomite manufacturing process and the required equipment. Dolomite processing: after the raw ore is mined, the large dolomite ore is crushed by the coarse jaw …

In this process, closed-end, nickel-chromium-steel alloy retorts are filled with a mixture of calcined dolomite ore and ferrosilicon, which are heated until magnesium crowns form. Each cycle takes about 11 hours, requires manually filling and emptying of the vacuum tubes, and uses about 11 tons of raw materials for every one ton of magnesium ...

producing expense in the practice. Dolomite is the primary ore employing for th is process. Since this kind of ore has the higher calcium oxide percentage comparing to magnesite, it has n ot generated the complex oxide MgO∙SiO 2. Thus, the amount of magnesium oxide attends in the procedure freely and the recovery efficiency go up dramatically ...

Magnesium oxide suitable for the use in basic refractories was prepared from dolomite (CaMg(CO 3) 2) by hydrochloric acid leaching, precipitation with CO 2 and thermal hydrolysis. Leaching of the dolomite ore in aqueous hydrochloric acid solution was investigated with respect to the effects of time on dissolution of the dolomite sample.
