Sulphur Extraction

The catalyst used is colloidal nickel sulphide. The sulphur is run off from the surface, and after filtering and washing is obtained as a paste containing 55 per cent, of water. After drying, a product is obtained which is more toxic than most other forms of sulphur and is very effective in agricultural work as a fungicide; the particles are almost of colloidal size, most being less than 15 μ.

Nickel Chemistry

Extraction of Nickel In 1899 Ludwig Mond developed a process for extracting and purifying nickel. The so-called "Mond Process" involves the conversion of nickel oxides to pure nickel metal. The oxide is obtained from nickel ores by a series of treatments including concentration, roasting and smelting of the minerals.

Extraction of Nickel from Spent Catalyst Using Biodegradable ...

Literature suggests that ethylene-diamine-tetraacetic acid (EDTA) has been proved as a successful chelating agent for the extraction of metals from soils and spent catalysts. EDTA, however, is quite persistent in the environment due to its low biodegradability, thus its use becomes a matter of environmental concern. Therefore, to minimize the potential environmental risks, a new chelating ...

Applications of Phosphorus

The principal alloys are those containing copper, tin, zinc, nickel, lead and antimony. The phosphorus is usually added in the form of phosphor-tin. Phosphor-coppers may be made by heating copper phosphate or copper turnings and phosphorus in crucibles at 600-800°.

Estimation of Molybdenum - Atomistry

In the analysis of molybdenum ores, a solution is best obtained by fusion with sodium carbonate and potassium nitrate and extraction with hydrochloric acid. In the case of iron and steel, the metal may be dissolved in a mixture of hydrochloric and nitric acids with gentle heating so that the iron is oxidised.

Chemical Properties of Arsenic - Atomistry

With iron, cobalt and nickel, alcoholic solutions of the salts should be used, since with aqueous solutions the resulting arsenide is contaminated with free arsenic. Zinc and manganese arsenides are readily hydrolysed and cannot be obtained by the above method, but are prepared by combination of the elements.

Arsenic Trichloride, As Cl 3 - Atomistry

In acid solution magnesium precipitates arsenic and liberates arsine; cobalt and nickel yield arsenides. Aluminium in the presence of a little aluminium chloride behaves like phosphorus and when heated with the trichloride at 130° to 150° C. produces the brownish-red arsenochloride, Al As 3 Cl 3 , which with water yields arsenic and aluminium chloride.

Ammonium sulfate - Wikipedia

Uses. The primary use of ammonium sulfate is as a fertilizer for alkaline soils.In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.
