  • Bantycock Quarry Extraction of gypsum | British Gypusm

    The process for extracting the highpurity gypsum and processing it into plaster products is outlined here and explained in further detail on the other tabs on this page The site preparation works for each part of the site are the same: Each stage is discussed in more detail below STEP 1 Removal of topsoil and subsoil These soils are removed using an excavator machine (see below), beforeThe process starts by extracting gypsum rock deposits from the ground using a ‘JOY mine cutter’ that scores away at the face of the gypsum rock This is then broken up and transported to the surface It’s homogenising time The rock is then crushed into smaller pieces and sent to the homogeniser, which allows for any variances in the gypsum size to be reduced, ensuring consistency inThe British Gypsum mining processGypsum extraction is currently taking place centrally within the site Operations are currently progressing north in the direction of Fernwood and Balderton (see aerial image, below) Under the current planning permission, these operations can continue until 31st December 2027, with the final restoration to be completed by 31st December 2029The Application Process British Gypsum
