As a commodity, mineral products have many things in common with the sale of other commodities. For example, buyers and sellers need to sign a sales contract to determine the price of the product, the quantity of the product, the quantity of delivery, the date, and the establishment of compensation for breach of contract. The difference between mineral products and other commodities is that in most cases it is difficult to determine its quality and the exact quantity. These will have to determine through testing and analysis, such as water, metallic taste, taste associated metals, impurities, etc., all of which are identified in order to ultimately determine the price and value of the batch of minerals. Therefore, the sale of mineral products should pay attention to the following points: 1. Both buyers and sellers must be honest and fair. 2, all kinds of tests such as water and weight, both need to be present. 3, the two sides must be recognized when sampling, there must be sufficient representativeness. 4. When the mineral products are sold to the big smelting refinery, the sampling, the inspection, and the sample analysis are often subject to the big factory. At this time, the sales staff must also go with the car. In order to supervise the representativeness of the sampling, the accuracy of the test, and the analysis of the sample. 5. The sample of the final analysis and analysis shall be in triplicate. Each party shall hold one copy and the third shall be sealed. When a party disagrees with the analysis result, it shall be referred to arbitration. 6, in addition to the main metals, the accompanying valuable metals and harmful impurities should also be analyzed frequently, accumulate data, so that when sales are in mind. 7. Pay close attention to the price fluctuations of mineral products related to the company. Pay attention to the policy changes and trends of the valuation of associated metals and the deduction of harmful impurities, so that the production indicators can be adjusted at any time. Achieve maximum economic benefits.
