砂矿粒度为-0.15毫米占95％,有用矿物大部分富存在-100+43微米级别中,重矿物含量较低(2-2.5％),重矿物中70％是钛铁矿,其次是金红石、锆石和重铝硅酸盐等。含粘土5％。试验采用一次粗选、一次扫选和五次精选的全螺旋流程。针对细粒级的特点,采用小直径螺旋(粗、扫选φ500毫米;精选φ400、300和250毫米),及控制薄矿流和小流速的操作法。试验是在连续性试验设备上进行的,处理能力为 Most of the useful minerals are present in the -100 + 43 micron scale with low levels of heavy minerals (2-2.5%), 70% of the heavy minerals are ilmenite followed by rutile , Zircon and heavy aluminosilicates and the like. Containing 5% clay. The test used a rough selection, a sweep and five selected full spiral process. For fine-grained features, small diameter spirals (coarse, swept 500 mm; fine 400, 400, and 250 mm), and thin-flow and low-flow control are used. The test was carried out on a continuous test equipment with a handling capacity of
