Lime use in gold processing – A review ScienceDirect
2021年12月1日 Lime is the generic term used to describe various formats of the reagent (National Lime Association, 1995; du Plessis et al, 2021)Formats include: quicklime – a dry reagent with calcium oxide (CaO) as the main component, produced from the calcination of limestone containing calcium carbonate (CaCO 3); hydrate or hydrated lime – a dry reagent which limestone, which is mostly calcium carbonate (CaCO 3) is heated in a kiln to produce quick lime (CaO) Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere However, some facilities recover a portion of the emissions eg for use in sugar refining and precipitated calcium carbonate productionCalculating CO Emissions from the Production of LimeQuicklime can then be reacted with water to produce hydrated lime (calcium hydroxide) Quicklime has a much higher available calcium carbonate equivalent percentage when compared to limestone and a slightly higher value compared Lime Pete Lien Sons, IncExample 1: A water sample is tested for phenolphthalein and total alkalinity If the phenolphthalein alkalinity is 10 mg/L as CaCO 3, and the total alkalinity is 52 mg/L as CaCO 3, what are the bicarbonate, carbonate, and hydroxide Lesson 10: Softening Mountain Empire Community
