眼看着宋局长口水就流出来了,董思萌赶忙倒了一杯水打断他,

“宋局,这是矿石样品的检测报告,您看下。”

说着双手递上桑博千里迢迢带来的文件。

宋局这才恋恋不舍的把目光从矿石上移开,打开文件袋,一张一张的仔细看起来。

“呦,还是SGS的检测报告,够下本儿的啊。”

宋局抬头看了一眼董思萌,对报告很是满意,他从不妄自菲薄,但是也很清楚现阶段华国在这些方面与发达国家的差距。

SGS集团即瑞士通用公证行,总部位于瑞士日内瓦,创建于1878年,是全球检验、鉴定、测试及认证服务的领导者和创新者,也是公认的质量与诚信的全球基准。

在全球拥有1,350多个分支机构和实验室、70,000多名员工, 服务网络遍及全球。SGS的服务对象包括国内外企业、政府和国际机构,服务范围覆盖农产、矿产、石化产品、工业品和消费品的检验、鉴定、测试、贸易保障服务和国际认证服务。近年来,公司的业务范围更扩展到环境、汽车、生命科学和节能减排等新兴领域。

当然了,这是后世的数据,现阶段还没有这么牛掰,但是一百多年的创建史和良好的口碑,使这家公司在各个行业的检测领域享有盛名,检测结果也算得上是最权威的了。

有过留学经历的宋局自然能看得懂这份纯英文的报告,专业素养告诉他,这不仅仅是一个金矿,里面的伴生物非常多,而且价值不低,关键是在一吨矿石里分离十种物质的成本比在十吨矿石的每一吨里分别分离一种物质的成本低很多。

尤其是,这还是在条带状含铁层金矿,为啥说这种矿石好呢,主要是金矿的选矿流程分为以下几部。

第一步就是矿石破碎,这几乎是所有矿石选矿的第一步,没啥好说的,不然矿石内部的东西根本就出不来。

第二步就是磨矿,也就是把第一步破碎出来的矿石碎渣进一步给磨成粉,能让矿石里的目标物质进一步的暴露出来,这一步通常是把矿石和水混合在球磨机里,通过摩擦和碰撞使矿石进一步细化。

第三步是矿浆分离,磨矿后矿浆里的颗粒大小不一,要通过不同大小的筛网过滤矿浆,将颗粒按照大小分为不同等级。
