Mineral Processing. Gypsum processing can be divided into three basic steps: (1) rock preparation, (2) calcining, and (3) formulating and manufacturing. This is illustrated graphically with the flow chart in Figure 1. The specifics of each step will vary with the quality of the gypsum and with the type of final product.

GMT Minerals is intending to establish a new front-end gypsum processing and handling facility near the deposit. The new front-end gypsum processing facility at Berbera will process about 2Mt/yr of gypsum and produce a homogenised, 50mm product that is suitable for pulverisation and calcination prior to use in board production.

Potential emission sources in gypsum processing plants are shown in Figure 11.16-1. While particulate matter (PM) is the dominant pollutant in gypsum processing plants, several sources may emit gaseous pollutants also. The major sources of PM emissions include rotary ore dryers, grinding mills, calciners, and board end sawing operations.

The following list outlines key material characteristics that affect gypsum processing. 1. Abrasive. Mined gypsum is a somewhat abrasive material. As a result, robust equipment must be used when processing gypsum …

The EGRS Gypsum Recycling System processes Waste Gypsum and Plaster Board, removes the paper and other non-gypsum particles, producing product equivalent to Gypsum – allowing the final product to be reused in Plaster Board manufacture and a number of other industries. This protects valuable natural resources by reducing the …

Gypsum is normally only screened to remove 'fines' (mainly mudstones), then crushed and finely ground. Gypsum/Anhydrite for cement manufacture is supplied in crushed form for further fine grinding with cement clinker. C.

When gypsum is heated at about 150–160 °C, it loses approximately three-quarters of its water in a partial dehydration process and becomes hemihydrate gypsum (CaSO 4 •½H 2 O) or calcined gypsum; it is also known as beta gypsum (alpha gypsum is made by processing batches of gypsum under elevated pressure). Calcined gypsum …

The Role of Drying in Gypsum Mineral Processing. After gypsum ore is extracted from mines or quarries, it is crushed and stockpiled as needed. If the gypsum ore's moisture content is greater than 0.5 weight percent, then the material requires drying.
