摘要
二小一贫矿床，其矿体平均厚度（〈5m）在薄一极薄矿体之间，均属难采矿体，采矿的贫化率极高，一般都在30％以上，最高可达60.70％。对这些矿开发利用时，一定要进行可行性论证和试生产验证，确保开发利用有利可图。
Small and poor deposits indicate that ore bodies have an average thickness less than 5m, belonging to thin and ultrathin ore body. Those ore bodies are featured by difficult in mining, higher in mining dilution rate, generally over 30% and maximum to 60 - 70%. Feasibility study and trial production are required for reasonable exploration and utilization of the ore bodies, ensuring that the development and utilization are profitable.
