在浮选生产过程中,常会碰到需对矿石进行预先脱泥、脱碳再浮选等情况。为了了解这些中间产物中金属流失的情况,从而正确估价工艺流程的合理性,需要掌握这些中间产物的产率和金属品位,以便计算出其中的金属分布率。理论上可通过采集原矿样、预浮产物样、预浮尾矿样(即下步的浮选给矿样),分析化验其中的有价元素品位,按公式γ=(β_原—β_给)/(β_浮—β_给)计算出这些中间产物的理论产率。但在实际上该法几乎无法实施,因为这三个样品中的有价元素品位一般相差不大,从而化验中的允许范围误差通过该计算
In the flotation production process, often encounter the need for pre-ore ore desliming, decarbonization and then flotation and so on. In order to understand the loss of metal in these intermediates and thus to properly evaluate the rationality of the process, it is necessary to know the yield and metal grade of these intermediates in order to calculate the metal distribution rate. In theory, by collecting raw ore samples, pre-floating product samples, pre-floating tailings samples (ie flotation to the next sample), the analysis of the value of the elemental value, according to the formula γ = (β_orogen - β_ / (Β_fw_β_suppose) to calculate the theoretical yield of these intermediates. In practice, however, the method is almost impossible to implement because the value of the value of the valence elements in the three samples is generally not far apart so that the permissible range error in the assay is calculated by the calculation
