摘要

为了对采矿业的废物进行有效管理，研究其物理和矿物学变化非常重要。为此，采用了 X 射线衍射 (XRD)、热重法 (TG)、导数热重法 (DTG) 和差热分析 (DTA) 等方法。使用 pH 值为 4.8 的醋酸铵缓冲溶液研究了在 800-850°C 温度下灼烧岩石后岩石中重金属移动形式含量的变化。获得的数据表明，矿物成分在岩石样本的热行为中起着重要作用，随后的热过程对重金属生物利用率的变化也产生了影响。

Thermal Impact on Heavy Metal Bioavailability in Burnt Rocks of Waste Heap of Chervonohradska Coal-preparation Plant (Lviv Region, Ukraine)

For effective waste management of mining industries is important to investigate their physical and mineralogical changes. For this purpose, X-raydiffraction (XRD), thermogravimetry (TG), derivative thermogravimetry (DTG), and differential thermal analysis (DTA) methods were used. Changes in the contents of mobile forms of heavy metals in rocks were investigated using an acetate-ammonium buffer solution with a pH of 4.8 after burning rocks at a temperature of 800–850°C. The obtained data indicated the significant role of the mineral composition in the thermal behavior of the rock samples and the subsequent influence of the thermal processes on the changes in the bioavailability of heavy metals.
