| A METHOD TO DETERMINE PRECIOUS METALS CONTENT IN POROUS MEDIA |
| In the newly-developed method, a sample is directed via a pipe on which generating and receiving frames are located. When a particle passes by the receiving frames, anomalies of the secondary magnetic field are registered. Comparing active and reactive components of the secondary magnetic field, size and specific electric conductivity of each particle are estimated. Based on these data, a sort of a metal and a weight of each particle are determined. Besides, weights of each metal sort particles are separately summarized. |

| CYANIDATION TECHNIQUE |
| The new technology differs in that the
separation of the solid fraction from the gold-bearing solution is achieved by
damping the pulp on to a waterproof ground and draining it after the cyanidation
by stirring is completed. |

| METHOD OF BIOGEOCHEMICAL EXPLORATIONS OF PLATINUM DEPOSITS |
| This method includes taking of
the samples of vegetation of dominating species, their bashing (burning),
subsequent analysis, determination of abnormal values of concentrations of
platinum together with the development of maps and judging on their basis of the
presence of ore bodies. |
