Abstract

This study was conducted to examine the recovery high-grade tin concentrate from the tin ore atWangpiri, Uljin by froth flotation. The optimum conditions were obtained by investigating various experimentconditions. It was found that Na2SiF6 acts as an depressant for the silicate gangue minerals, main componentof crude ore and alkyl-hydroxamic acid was used as a collector because of its better selectivity and strong collectingforce. High-grade tin concentrate with Sn grade of 75.55% and with recovery of 89.86% was obtained under thefollowing conditions; depressant 1,000 g/t, pH 5 adjusted with sulfuric acid, collector 600 g/t, frother 20 g/t, 3-timerepetition of cleaner flotation with the rougher concentrate. It has been found that an effective and simple tinflotation process was achieved by comparing with the previous results and separation efficiency using oleic acid.

본 연구에서는 경북 울진 왕피리 주석광을 대상으로 고품위 주석 정광 회수를 위한 부유선별을 수행하였으며, 다양한 조건변화 실험을 통해 최적조건을 규명하고자 하였다. 원시료의 대부분을 구성하고 있는 규산염맥석광물을 효과적으로 억제하기위해 실험을 통해 Na2SiF6를 최적 억제제로 선정하였으며, 포수제는 선택성이좋고 포집력이 강한 알킬-하이드록삼산을 사용하였다. 실험결과, 억제제 1,000 g/t-H2SO4(pH 5 in pulp)-포수제600 g/t-기포제 20 g/t의 순서로 시약을 첨가하여, 얻어진 조선정광을 대상으로 정선횟수 3회를 거쳐 Sn 품위와회수율이 각각 75.55%와 89.86%인 고품위 주석 정광을 회수하였다. 또한 본 연구의 결과와 기존 연구결과와의선별효율을 비교한 결과 공정의 간소화 및 선별효율의 증대로 본 연구에서 효율적인 석석 부유선별이 가능한 것으로 나타났다.
