APPARATUS AND METHOD FOR DISSOLUTION EXPERIMENT OF PARTICULATE MINERAL

摘要

PURPOSE: An apparatus and a method for dissolution test of particulate minerals are provided to quantitate the dissolution of minerals, which occurs in the nature world over the long-term by accelerating dissolution using a particulate mineral sample. CONSTITUTION: An apparatus (100) for dissolution test of particulate minerals comprises: a mounting member (10) comprising a concave receiving unit (13) which contains a particulate mineral sample (s) and has the open upper portion and an exhaust passage which is connected to the receiving unit for discharging a pH adjusting solution which passed through the particulate mineral sample; a filter (20) which is placed at the front end of the exhaust passage and allows the pH adjusting solution to pass but the particulate mineral sample cannot pass through; a cover plate (30) which is inserted into the receiving unit and is placed on the upper portion of the particulate mineral sample; a pressing element (40) which pressurizes the cover plate in a particulate mineral sample direction; an injection device for injecting the pH adjusting solution to the receiving unit; and a discharging tank (60) which collects the pH adjusting solution discharged through the filter.
