我们的钽铁矿，进口自埃塞俄比亚；

钽铁矿，如照片所示，灰黑色；

我们交易方式如下：

货发到我们在香港的仓库；邀请AHK的矿产品分析专家，提供样品给他们寄到AHK在英国的总部进行检测；

基于检测结果中五氧化二钽（Ta2O5)的含量，我们再给予结算货品金额。

买家付款后，我们在香港的仓库会安排出货（包装好的矿物）。

我们每月的产量：5000kg；

如果订单少于2000kg，我们可以安排空运。

五氧化二钽的含量每次都会不一样，所以我们每一票货都会邀请矿产品分析专家检测五氧化二钽的含量。

运费和仓储费由我方承担。

We mine in well known Tantalite producing area Kenticha in Ethiopia.  

Tantalite is Grey Black mineral as the photo.

How we deal is:

Ship to warehouse in Hong Kong and invite assayer Alfred Knight (AHK) to take a sample to be analyzed in England head quarter.  Upon the result of percentage of Ta2O5, we calculate the amount based on agreed $ price/kg or LB. 

Buyer pays to our account in bank and warehouse releases the sealed mineral.

Our production is rather small, 1,000-5,000 kg a month.  If it is less than 2,000 kg, we send it by AIr.

Percentage of Ta2O5 depends on concentrate in Ore each time.  That is the reason we use Assayer to be between seller and buyer for each shipment.  Sample would not make much.  Shipping and storage cost on me, so buyer does not loose anything in case.
