This article provides information on DNA extraction from plant tissues, their methods, and the effective STAB method. It also provides detailed information on the tools required to implement the STAB method, the reagents, and the sequence of operations.

The paper considers the most effective leaching solution for extracting gold; it was decided to test different reagents using the IW method from spent uranium gold wells. And also Scientific experiments were carried out to extract gold from a productive solution in laboratory conditions, the sorption process was carried out on various grades of activated carbon to determine a promising sample. In order to saturate the sorbent with a solution from a productive solution, studies were carried out with the following types of activated carbons: AG 3, AG 5, AG-95. The sorption process was carried out with a productive solution supplied from the bottom up and consisting of a pressure column, with a dense layer of activated carbon 3 kg.
