activity in that case meant a loss of biodiversity1. The development of a gypsum quarry creates the favorable conditions that provide habitats for photophilic and ther-mophilic (light and heat demanding) species, orchids, gentians and carnation because “disturbance ecology” can take place in and under: 1. Areas which are exposed to light thanks to the removal of tall-growing vegetation; 2

the case of the Moncalvo sinkhole event (Piedmont, NW Italy) Sabrina The Moncalvo gypsum quarry has been working since 1993 and actually consists of 12 km of drifts, which are organized on three regular superimposed sublevels, connected by a helical ramp, between 170 and 113 m a.s.l. An older open pit quarry is also present near the underground quarry (Fig. 4). A survey campaign with three

The exotic rocks in the quarry area could either have been brought to the site as tools (as in the case of the Widan el-Faras basalt quarry, Harrell andBown 1995, Harrell 2002) and/or as blanks of vessels or other objects. In either case, it is likely that they were connected to the gypsum quarrying and then reused for grindingstone production. Pottery was limited to a few scattered fragments

Based on the current predicted rates of extraction, it is anticipated that the existing permitted gypsum reserves will be used up by 2024/25. To ensure we have access to high-grade gypsum beyond this date, we are submitting a planning application to extend the quarry to the south.

01/04/2021 Only in a few cases gypsum quarries have been clearly identified: this is the case for the Roman anhydrite-gypsum quarry of the Marsa Nakari port in Egypt (Harrell, 2010). These quarries are still well visible, with their decametric open rectangular cuts and up to 3-metre high vertical confining walls. Their surface exposure, even in this rather arid climate, has erased all traces of original

Fast cycling conveyor In this long-established quarry the first conveyor after the crusher is only 18m long, meaning that it cycles very quickly. This, combined with the high abrasiveness of the material, was necessitating its replacement every two weeks. The client was counting on an increased conveyor belt lifetime.
