A Measurement Of The Mobile Forms Of Metals And Its Indication Of Concealed Orebody In The Rare Metal Vein Of Jiajika

The rapid development of the economy is increasingly demanding mineral resources,but the mineral resources in the exposed areas have been exhausted,and new prospecting targets should be placed in concealed areas.The Measurement of metal activity as a new geochemical exploration technology is widely used in the coverage area with good prospecting effect.The JiajikaDiggings is the largest pegmatite-type lithium mine in China and also has a variety of rare metal resources.Taking the Jiajika mining area as the research object,the measurement of metal activity was used for ore prospecting research.By studying the sampling medium;active state extractant and extraction process;Activity measurement in the test area and the element migration mechanism,We get the following understanding:1)Because the physical weathering of the mining area is very serious,the soil particles are coarse,and mainly silt sant.The determination of the total amount of soil fine-grained material in this area can't indicate the location of the concealed ore body.Therefore,the metal activity state mainly based on selective extraction is considered as aeffective solution in prospecting research.2)Research on metal activity states focuses on extractants.The weak extractant based on deionized water and neutral solution potassium sulfate can extract the metal active state very effectively in the extraction processand achieve the indication effect on different types of concealed ore bodies.3)Under the condition that the measurement effect of metal activity state reaches the expectation,the ground gas measurement is carried out above the known typical concealed ore body,which indicates that the elements in the mining area migrate from the deep ore body to the ground gas.
