Original Abstract

Waste rock dumps in the aftermath of pegmatite mining enable the growth of healthy populations of Larix sibirica in, for the forest unsuitable semi-arid steppe habitat, the Khentii Mountains, Mongolia. Trees can thrive in such extreme habitats due to water vapour condensation and adsorption in the topsoil of a dump. During the growing season 2015–2017, continual measurement of thermal regime (hourly) was carried out at the depths of 10, 30 and 60 cm in the dumps and surrounding steppes. At the depth of 10 cm, temperatures (up to 40% of cases) enabling dew formation in dumps, in the time period of the highest possible air humidity (2 a.m. to 8 a.m.) were confirmed there. The suitable temperature conditions to form dew were found primarily at the beginning of the growing season characterized by a low precipitation. Later in the growing season with the following increasing precipitation, the temperature potential of dumps for dew formation decreased continuously. The cross-correlation indicated active exchange of heat between the atmosphere and the dump up to the depth of 30 cm. The outcomes further indicate that water vapour adsorption shall contribute significantly to the moisture regime of dumps and the effective porosity of sandy soils of dumps is likely to form ideal conditions for it. The construction thickness of the cover soil material between the depths of 30 and 60 cm with the predefined physico-chemical properties can be recommended to augment the potential of the dew yield in future projects. Effective water vapour condensation and adsorption may support success of landscape afforestation or reclamation of mining areas in arid or semi-arid conditions.
