In recent decades, decreasing metal ore grades and the complication of the mineral composition of ores have been observed due to the depletion of high-grade raw materials, and therefore low grade ores and mining wastes are considered as the most promising sources of different metals [7, 8].
Materials and Methods  The object of the study was a sample of uranium ore from the Vostok deposit (Northern Kazakhstan), which was subjected to long-term acid leaching.

Therefore, this research suggests paying more attention to the mixing and blending processes of the materials to achieve a more uniform distribution.
Cellular lightweight concrete (CLC) can be used in various construction materials, including lightweight bricks.
The difference between AAC and CLC lightweight bricks lies in their drying process and forming materials.
The production of CLC lightweight bricks involves several materials, including Portland cement, fine aggregate (sand), water, and a foam agent.
