Sequential leaching experiments indicate fluorine in carbonate rock, phosphorite and Mo-Ni ore layer occurs principally in dissolvable forms: water-soluble, associated with carbonate or phosphorite, so fluorine in which rocks have high chemical mobility at surface conditions. Fluorine in siliceous rock, black shale and carbonaceous slate mainly occurs in undissolvable forms, which are inert at surface conditions.

氟在碳酸盐岩、磷块岩、钼、镍等多元素富集层及部分硅质岩中主要以水溶态、碳酸盐结合态等易溶形式存在，其在自然条件下的化学活动性强；而氟在碳质板岩、黑色页岩及大部分硅质岩中主要存在于难溶矿物中，其化学活动性较弱。

It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...
