海滨砂矿开采是海洋采矿的一个重要组成部分,主要矿物类型有钛铁矿、锆英石、金红石等.澳大利亚、斯里兰卡和印度从海滨砂矿回收的重矿物占世界总产量的70％左右,其中澳大利亚生产的钛铁矿占世界总产量的58％(其中的49％集中在西澳),金红石占85％,锆英石占70％。澳大利亚海滨砂矿的开采已有100多年的历史,重矿物的产地集中在东海岸的布里斯班(Brisbane)至纽卡斯尔(Ncw Seaside placer mining is an important part of marine mining, with the main mineral types being ilmenite, zircon, rutile, etc. The heavy minerals recovered from seashore plains in Australia, Sri Lanka and India make up about 70% of the world’s total production, Among them, ilmenite produced in Australia accounts for 58% of the world’s total output (49% of which is in Western Australia), 85% of rutile and 70% of zircon. Australian seashore placer mining has been in existence for more than 100 years, with heavy minerals originating in the east coast of Brisbane to Newcastle (Ncw
