Calcination sentence examples calcination was primarily based upon certain experiments on combustion and calcination , and in effect reduced the number of the alchemical principles, while setting up a new one, a principle of combustibility, named phlogiston (from (PXoyun-6s, burnt). Roasting is the process of converting sulphide ores to oxides by heating the ores in a regular supply of air at a temperature below the melting point of the metal. An example of roasting is when Zinc sulphide is converted into zinc oxide. 5. The types most commonly in use are fluidized-bed, multiple-hearth, flash, chlorinator, rotary kiln, and sintering machine (or blast roaster). The process of smelting is that in which ore is melted with a flux and often with a reducing agent, and it involves, calcination, roasting and reduction. Giving examples, differentiate between 'roasting' and 'calcination'. Example: Roasting ZnS may yield ZnO; roasting HgS may yield free Hg metal. Non-metals are the elements which form negative ions by gaining an electron. Examples: Carbon (C), Sulphur (S), Phosphorous (P), Silicon (Si), Hydrogen (H), Oxygen (O), Nitrogen (N), Chlorine (Cl), Bromine (Br), Neon (Ne) and Argon (Ar) etc. 51 called smelting. The calcination process normally takes place at temperatures below the melting point of the product materials. The residue may remain as a powdery substance (a calx), in which case the process of roasting is termed calcination; or it may be a pasty mass or liquid.

This process is known as roasting Example of roasting 2ZnS+ 3o2 ----- 2Zno + 2SO2 The carbonate ores are changed into oxide by heating strongly in limited air. Calcination is a thermal treatment process in presence of air applied to ores and other solid materials to bring about a thermal decomposition, phase transition, or removal of a volatile fraction. Calcination is commonly used for carbonate and bicarbonate ores, while roasting is more commonly used for sulfide ores. eg : 2 ZnS +3O 2-----> 2 ZnO + 2SO 2. CALCINATION OR ROASTING OF ORES.

As silica membranes generally require 3 to 6 silica thin film coating, where calcination is applied after each coating, then the calcination step for a silica membrane may take up 6–12 days. As an example, a single silica thin film calcination of up to 650°C and 0.5°C min − 1 requires 22 h to heat up and 22 h to cool down, plus an average of 4-h dwell time, totaling 2 days. Often before roasting, the ore has already been partially purified, e.g. An example of calcination is the processing of calcium carbonate (CaCO3) ore. This process is known as calcination Calcinaton example reaction Znco3 ----- ZnO+ co2 CaCO3 → CaO + CO2(g) 3 23 2 ) Examples Limestone is heated co2 is given off then limestone is said to be calcined.
