我國(guó)深層鹵水找鉀獲重大突破

發(fā)布時(shí)間：2014-11-07 06:05:57 來(lái)源：經(jīng)濟(jì)日?qǐng)?bào) 作者：佚名責(zé)任編輯：羅伯特

　　本報(bào)北京11月6日訊記者祝君壁從國(guó)土資源部獲悉：在由中央地勘基金投資實(shí)施的青海省柴達(dá)木盆地西部大浪灘礦區(qū)、昆特依礦區(qū)深部，日前新發(fā)現(xiàn)平均厚度581.74米至681.11米巨厚沙礫石層孔隙鹵水礦層，鹵水中氯化鉀平均品位在0.30%至0.48%，單井涌水量最大達(dá)6000立方米/天，降深19.6米。這兩個(gè)項(xiàng)目的成功實(shí)施，預(yù)計(jì)可提交氯化鉀資源量超過(guò)2億噸，潛在經(jīng)濟(jì)價(jià)值千億元以上，不僅意味著我國(guó)深層鹵水找鉀工作取得重大突破，也標(biāo)志著我國(guó)深部鉀鹽勘查工作步入新階段。

　　全球鉀鹽產(chǎn)品95%用于化肥。我國(guó)作為13億人口的農(nóng)業(yè)大國(guó)，卻相對(duì)缺鉀，已探明氯化鉀地質(zhì)儲(chǔ)量占世界儲(chǔ)量比例不到3%，對(duì)外依存度居高不下。2014年度實(shí)施的大浪灘和昆特依2個(gè)項(xiàng)目，預(yù)示柴達(dá)木盆地深部存在找鉀巨大潛力，可有效緩解我國(guó)鉀鹽企業(yè)資源緊缺局面。
