reaction of barite with coke

Dolomite produces a very weak reaction to cold dilute hydrochloric acid however if the acid is warm or if the dolomite is powdered a much stronger acid reaction will be observed (Powdered dolomite can easily be produced by scratching it on a streak plate ) Dolomite is very similar to the mineral calcite Abstract The effect of the moisture content of barite-coke paste on the kinetics of carbothermal reduction was investigated to understand the role of extrusion technique on this type of solid-gas reaction The pastes were formulated using the typical natural barite and coke powders normally used in the industrial scale 0 65 wt % carboxyl

The purpose of this study was to liberate gold from sulfide minerals in a gold concentrate through microwave-nitric acid leaching and to separate the light minerals in an insoluble residue using a hydro-separation process The representative sulfide minerals in the gold concentrate were pyrite with minor galena

Oct 14 2009Barite is processed by carbothermal reduction (heating with coke) to give barium sulfide Barium sulfate produced in this way is often called blanc fixe which is French for permanent white Blanc fixe is the form of barium encountered in consumer products such

Preparation: Barium sulfate is obtained in commercial amounts from the mineral barite after mining and processing The processing of the impure barite involves heating it with coke (carbon) to form the water-soluble barium sulfide (BaS) which is then separated from the impurities and reacted with sulfuric acid to give the pure barium sulfate

Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4 It is a white crystalline solid that is odorless and insoluble in water It occurs as the mineral barite which is the main commercial source of barium and materials prepared from it The white opaque appearance and its high density are exploited in its main applications

Experimental results show that grain size of either carbon material or barite ore has not appreciable effect on the reaction rate Kinetic analysis of the experimental data revealed the rate is strongly controlled by the chemical reaction of carbon gasification (Boudouard reaction) The reaction rate is very considerably related to the type of

pH is a measure of how acidic or basic a chemical is when it's in aqueous (water) solution A neutral pH value (neither an acid nor a base) is 7 Substances with a pH greater than 7 up to 14 are considered bases Chemicals with a pH lower than 7 down to 0 are considered acids The closer the pH is to 0 or 14 the greater its acidity or basicity respectively
