石英砂是一種非金屬礦物質，具有堅硬，耐磨的特征，顔色多數爲乳白色，之一種重

要的工业矿物原料，石英砂广泛应用在玻璃铸造，陶瓷，以及耐火材料，也经常用在

冶金，建築，化工，塑料，橡膠等工業原料。

石英砂中的礦物含量較大，以石英爲主，其次爲長石，雲母岩屑，黏土礦物。由于石

英具有較G的耐火性能，工業上將石英分爲：普通石英砂，*制石英砂，G純度石英

砂，叫做矽砂。

工業上的石英砂原料品味越來越低，爲滿足工業上的需求，可以通過選礦來提G，看

具體的提純方法有以下幾種：

1.擦洗脫泥。

借助機械力和沙粒建的磨剝力來除去石英砂表面的泥性雜質，和進一步擦碎未成單體

的礦物集合體，在經過進一步的分J來提純石英砂的效果。

2. 磁选

可以去除石英砂中國的此行礦物，比如通過強磁性及去除赤鐵礦，褐鐵礦，黑雲母等

弱磁性礦物。

3，浮選

浮選用于除去石英砂中的長石，雲母等一些磁選無法除去的雜質，進一步提G其純度

。

4，酸浸。

酸浸是利用石英不溶于酸（HF酸除外），而其它雜質礦物能被酸液溶解的特點，可以實現對石英的進一步提純。

5，微生物浸出。

是指利用微生物浸除石英砂顆粒表面的薄膜鐵或浸染鐵，這是新近發展起來的一種除鐵技術。

"I can't do it," he gasped, "I can't really. You must—excuse me." "Why, what's this?" he exclaimed. "What does the game mean?" (1.) Can the driving power be employed directly to shift the belts of a planing machine?—(2.) Why are planing machines generally constructed with a running carriage instead of running tools?—(3.) What objection exists in employing a train of spur wheels to drive a planing machine carriage?—(4.) What is gained by shifting the belts of a planing machine differentially?—(5.) What produces the screeching of belts so common with planing machines?—(6.) What conditions favour the shifting of planing machine belts? “Stuck. It won’t come back. It’s the jinx! Hoodoo! We’re heading down for the bay and I can’t get the nose up!” "Yes," he said, emptying the soap-caked water from the Indian basket wash basin upon the earth floor;[Pg 27] "why?"—"I used to know him in '61. He came up to the Mescalero Agency then, not long before the Texans overran the place. I recollect there was a sort of blizzard and it was seventeen below. He came after a kid me and another feller'd been looking after. Pretty little cuss, about four years old. I gave her her first bow'n arrow." "Say!" she apostrophized. "Cor—po—ral Ell—iott. Cor—po—ral Ell—iott!" "But that's the point—don't you see?" As luck would have it, the only piece that was not his was the Moor's most characteristic feature, the knob of firs that made it a landmark for miles round. While they still stood men could still talk of and point at Boarzell, but when he had cut them down, grubbed up the gorse at their roots, ploughed over their place—then Boarzell would be lost, swallowed up in Odiam; it would be at most only a name, perhaps not even that. Sometimes Reuben shook his fist at the fir clump and muttered, "I'll have you yet, you see if I d?an't, surelye." HoME WWW822WWWSSCOM ENTER NUMBET 0010www.bitray.com.cn
