Notice: The analysis index for gold, silver and sulfur in copper concentrates should be informed and the particle size should be marked. There can not be radioactivity for the elements. The elements exceed the standard can be accepted by reducing price. |
This standard is applied to the copper concentrates products getting from mineral processing and used for copper smelting.
(Please inform the content of the following elements)
(1) The moisture content in the concentrates should be less than 14%,and also less than 8% during heating-period.
(2) Other impurities should not be mixed into the concentrates.
(3) Packing: The concentrates most have been delivered by bulk transport and container transport, packed with 1-2 tons bag. The same grade can be classified as one lot.
3.Inspection Method
The inspection carried out at the loading port to determine the letter of credit amount. The inspection carried out by AHK, ALEX, SGS or CCIC at the port of discharge should be final for both parties. Moreover, the five necessary items (lead, fluorine, arsenic, mercury and radioactivity) should pass the inspection of China Customs
