Lime in the Sugar Industry. Hydrated lime is essential to the production of sugar from both sugar cane and sugar beets. It is also used to purify sugar derived from other sources, such as maple or sorghum. Sugar cane and sugar beets are harvested and processed with water to form raw juice, which has low pH and contains dissolved impurities.

Calciment®, a co-product of the lime manufacturing process, is a dry bulk product with similar attributes to quicklime along with unique pozzolanic properties accredited to the presence of the pozzolans silica and alumina. Calciment offers fast drying, modification of high clay soils, as well as short and long term strength gains.

11.17 Lime Manufacturing 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.

Production. In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones. Uncommon sources of lime include coral, sea shells, calcite …

The re-carbonation process is essentially the opposite of the calcining/burning process (see "Lime production process"). Both quicklime and hydrated lime when exposed to the air for too long begin to draw in carbon dioxide from the atmosphere. This therefore replaces the oxide component of the chemical and turns the lime roughly back to its ...
