METHOD FOR SEARCHING ORE DEPOSITS ON MICROAMALGAMS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC G01V9/00 

FIELD: mining.

SUBSTANCE: gas samples are taken from soil horizon and subsequently passed through each part of absorptive system. The latter consists of two parts of golden sorbents. The first part of the above system consists of one sorbent and speed of sample passing through it is not more than 5 l/min. The second part of the system consists of some number of golden sorbents, each of which provides the sample passage with speed of not more than 1 l/min. Available deep ore objects are estimated by content of mercury accumulated on sorbents at various pumping speeds. In order to implement the method, the device which includes gas sampling cap connected through dust collecting filter and three-way valve with mercury absorbing filter and absorptive system is proposed. Absorptive system is connected to measuring unit of mercury photometre and power supply unit, which are connected to each other. Measuring unit of mercury photometre is connected to vacuum pump with controlled pumping function.

EFFECT: more reliable searching results.
