In the leaching experiments, sulphuric acid was used which made by Merck with a purity of 98% and a density of 1 ...


Waterborne boron may be adsorbed by soils and sediments. Adsorption–desorption reactions are expected to be the only significant mechanism influencing the fate of boron in water (Rai et al., 1986). The extent of boron adsorption depends on the pH of the water and the concentration of boron in solution.

After the boron-concentrate was dried, crushed, and ground ( ore less than 74 µm). The boron-concentrate and ammonium sulfate were mixed according to the specific ammonium-magnesium ratio (1.6).


Concentration Definition:. The process of removal of the gangue from Ore is known as Concentration or Dressing or Benefaction. There are numerous methods of concentration and the methods are chosen based on the properties of the ore.


The largest deposits of boron ores within Turkey are concentrated within the Emet (Kütahya province) and Kirk (Eskisehir province) regions. The deposits within the USA are mostly situated within the Mojave desert within the California state, and also within the Utah and Nevada states.


Boron was discovered by Joseph L. Gay-Lussac and L. J. Thénard in 1808 that was around 60% pure. The pure form of boron was isolate by Henri Moissan (French chemist) in 1892 and then in 1909, almost pure boron was isolated by Ezekiel Weintraub. The name borax has been originated from buraq (Arabic) and burah (Persian) meaning "white" [1].

Although the total amount of boron resources in China is high, the grades of these resources are low. The authors have already proposed a new comprehensive utilization process of boron-bearing iron concentrate based on the iron nugget process. The present work describes a further optimization of the conditions used in the previous study. The effects of …


The word "ore" is herein used to include both categories. Saline solutions of boron compounds are readily concentrated by this process. I use the term "boric acid" to designate either sassalite or, more commonly, the boron compounds resulting from the treatment of the ores of boron by acidic materials.


Boron can be found in surface water and groundwater, the latter is highly affected by wastewater discharges. Based on WHO. 2. guidelines, boron concentration in groundwater varies from less than 0.3 to more than 100 mg L-1. throughout the world[7]. This guideline also called for a provisional boron concentration of 0.5 mg L-1


content) of iron ore concentrate generated in a steel company in Northeastern China, boron mud selected, and bentonite used in this experiment were listed in Table 1. The TFe content in iron ore concentrate was 65.76%, B 2O 3 content in boron mud was 3.80%, MgO content in boron mud was 35.94%, and SiO 2 content in bentonite was 63.00% ...


an ore of boron consisting of hydrated sodium borate; used as a flux or cleansing agent. Boron noun. the chemical element of atomic number 5, a non-metallic solid. Borax noun. a white compound which occurs as a mineral in some alkaline salt deposits and is used in making glass and ceramics, as a metallurgical flux, and as an antiseptic.


Abstract: In order to reasonably use the boron-concentrate ore from magnetic separation of Liaoning ludwigite, the raw samples were roasted with ammonium sulfate. Then the roasted materials were separated by filtration after being dissolved into water. The boron-rich solution was used to recover boron acid while the remaining residue was used as a raw material for …


Boron-containing iron ore concentrate/epoxy composite performs relative good 60Co γ ray shielding ability and its linear attenuation coefficient (μ) is …


Our products have a high concentration of boron. Titration is better suited than other methods for measuring boron in this high concentration range: When determining the percentage of B 2 O 3 in sodium borate and boric acid product samples, with high concentrations of boron, the most accurate method is titration.
