Arbuscular mycorrhizal fungi in a semi-arid, limestone

The main goal of this study was to determine the diversity and activity of arbuscular mycorrhizal fungi (AMF) in an area degraded by limestone mining within the semi-arid region of Brazil known as the caatinga (shrublands). Near a limestone quarry, we selected two areas of caatinga (preserved and degraded) for study. The number of glomerospores did not differ significantly between the two areas.

Biodiversity offsets in limestone quarries: Investigation

2018-8-1 Seeking to contribute to advance understanding of the current gaps and challenges, biodiversity offsetting required for environmental approval of three limestone quarries in compliance with Brazil's Atlantic Forest Act, a federal law that aims at protecting this biodiversity hotspot, were investigated. Both protection and restoration offsets were applied at area ratios from 1:1.1 to 1:5.

Co-products from the limestone mining as sources of

2021-5-1 The co-products from the limestone mining of the Irati Formation, which consist of limestone interlayers with bituminous shale, showed the potential to be used as sources of secondary macronutrients. This was possible due to the increase of Ca 2+,Mg 2+ and S-SO 4 2− contents; layer 2 was more effective in increasing the latter.

Limestone extraction underground mining

2021-3-22 Surface limestone mining. All over the world, the limestones are generally mined from a quarry or the open pit mining. It is the easiest way to remove the limestone without causing much destruction. In surface mining or open pit mining, the top soil and the overburden covering the mineral is removed. Then by the process of drilling the rocks or

A procedure to evaluate environmental rehabilitation

2010-11-1 In addition to the environmental impacts associated with most mining activities, limestone quarrying has the potential to cause a particular set of impacts due to the karstic nature of the terrains (Van Beynen and Townsend, 2005, North et al., 2009).Karst landscapes feature valued ecological and cultural resources, such as archaeological and paleontological sites, caves and landforms, unique

The company owns a mining title encompassing an area of 50 ha and it has recently applied for an extension of its mining title to an exploration permit for an area of 246 ha, as shown in Figure 1 (UTM SF-23). The deposit is a limestone orebody surrounded by gneiss.

Phytosociological studies on natural establishment of

ABSTRACT. Phytosociological structure was studied in limestone mining quarries at Rio Claro, São Paulo, Brazil. Quarries presented a chronosequence, ranging 1 to 40 years old, with focus on vegetation community organization, floristic similarity and plant diversity of three areas in different successive stages, devastated by limestone mining.

Limestone extraction SOLANCIS

Limestone mining is done out in the open. Once studies show the existence of stone at the site, the extraction is made by separating the rock in quarry benches and dividing it into blocks. Before beginning the quarrying process, a resource analysis is made. This study investigates the existence and quantity of stone at the site and also the
