Fluorite is a crucial material for the development of national strategic emerging industries. It is considered one of the critical minerals by the international community. Research on the positioning and prediction of hidden ore bodies is urgently needed as the discovery of fluorite outcrops has been exhausted. This paper provides a brief discussion on fracture-controlled vein-type fluorite deposits,including their nature,vertical zoning pattern and ore-forming processes. We also review the prospecting techniques commonly used in exploring vein-type fluorite deposits. By combining prospecting indicators and ore-controlling factors,we have developed a prospecting mod-el for locating and predicting hidden and semi-hidden fluorite ore bodies. We have identified two types of hidden fluorite ore bodies:"zoned" and "buried",and have proposed corresponding prospecting techniques and methods.This study established a four-step prospecting model and exploration technical flow for predicting the location of concealed fluorite ore bodies using geological,geophysical,geochemical,and remote sensing methods. The re-search is significant for guiding ore prospecting and exploration of concealed hydrothermal vein-type fluorite veins.
