興業銀錫(000426.SZ):銀漫礦業是國內罕見以錫、銀為主,共伴生鉛、鋅、銅、銻的複雜難選礦石
格隆匯6月14日丨有投資者向興業銀錫(000426.SZ)提問:本次銀漫礦業停產是處於什麼原因?
興業銀錫回覆:近幾年,隨着銀漫礦業地質科學研究工作的深化,在礦牀類型、礦體賦存規律、礦石特徵及礦物組成時空演化特徵方面取得了長足的進展,銀漫礦業自2023年起擬採礦石性質為富錫低硫型原礦,與以往所採淺部低錫高硫型難選礦石存在差異性。銀漫礦業是國內罕見以錫、銀為主,共伴生鉛、鋅、銅、銻的複雜難選礦石,為解決銀漫礦業錫石粒度細、易碎、回收率偏低等關鍵問題,實現資源高效、綜合回收利用,使銀漫礦業的選礦工藝與未來擬採礦石性質更加匹配,進一步提高銀漫礦業錫的選礦回收率和礦石入選品位,從而提升銀漫礦業的企業效益,銀漫礦業攜手北礦院、中國礦業大學、廣州院等科研院所組建專項科研團隊,深度合作創新研發,取得了突破性的進展,通過科技創新和工藝研發,提出“智能拋廢-強化分級-優先選硫-分級重選-高效脱泥-微細粒機柱聯合”工藝及設備創新集成優化方案。目前,本次技改的前期科研技術儲備及初步試驗研究工作已完成,因接下來的技改施工項目與生產系統相互制約,故需要進行停產技改。
