sulfide ores. (Nickel sulfide concentrates contain 6–20% nickel and up to 30% sulfur.) SO. 2. releases can be as high as 4 metric tons (t) of sulfur diox-ide per metric ton of nickel produced, before con-trols. Reverberatory furnaces and electric furnaces produce SO. 2. concentrations of 0.5–2.0%, while flash furnaces produce SO. 2 ...

The conventional nickel smelting and refining is the dominant strategy for nickel production from the sulfide nickel ores. The main disadvantages are the significant amount of SO 2 emissions during smelting and complex refining processes. In this paper, the authors investigated a solid-state nickel extraction method that recovered nickel …

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

The extraction of nickel electrolytic iron residue was controlled in different process conditions.The results showed that the extraction rate of iron,nickel,copper increase with increasing temperature.Most of iron,nickel,copper of nickel electrolytic iron residue can be extracted by 20% sulfuric acid when controlling reaction temperature ≥60 ℃,reaction …

The development of highly efficient, low-cost and stable electrocatalysts for overall water splitting is highly desirable for the storage of intermittent solar energy and wind energy sources. Herein, we show for the first time that nickel can be extracted from NiFe-layered double hydroxide (NiFe-LDH) to gene Most popular 2018-2019 materials …

The p-toluenesulfonic acid-based DES-1 (PEG-400:PTSA) and DES-8 (ChCl:EG:PTSA) showed high nickel extraction (>90 %). The effect of time, temperature, and solid to liquid ratio on nickel extraction was investigated. Selective nickel extraction was obtained under the pulp density of 20 g/L, a temperature of 100 °C, and a leaching …

Ni is extracted from it by four processes-. (i) Condensation: by oil-froth floatation process. (ii) Roasting. (iii) Smelting & Bessemarization: A mixture of NiS, CoS & CuS is obtained, which is called "Nickel Matt" that contains- 55% Ni. From Nickel Matt. Ni is collected by Mond or Orford's process. It includes the following steps: Three ...
