Thermoelectric Characteristics of Magnetite and Its Application:A Case Study of Bayan Obo Deposit
摘要
Abstract
Thermoelectric typomorphism of pyrite has been widely used in prospecting and prediction of gold deposits.However,the thermoelectric characteristics of magnetite and its application in prospecting are rarely reported.Taking the main mining area of Bayan Obo Iron deposit as the research object,the thermoelectric co-efficient measuring instrument BHTE-08 has been used to test and study the pyroelectric property of magnetite.The results show a significant thermoelectric anomaly in the eastern part of the main mining area,which is close-ly related to the occurrence of metal sulfides(especially pyrite and pyrrhotite)through microscopic observation.In particular,the proportion of magmatic magnetite in this anomaly area is high,so it is speculated that mag-matism leads to a large amount of magnetite and sulfide accumulation in this area,which may be a channel for deep magma ascent.This understanding is important and significant for deep prospecting in Bayan Obo's main-east mining area.In addition,the thermoelectric properties of magnetite and pyrite mixed samples in different proportions under artificial conditions are tested,and it is considered that the pyroelectric characteristics of mag-netite have broad application prospects and practical significance in evaluating the quality of iron ore.关键词
