我是一颗岩石I Am a Rock
我从矿山深处而来。体内藏着金属矿脉，也裹着大量无用的废石。在传统选厂，我们会被不分好坏、全部磨成粉。 I came from deep in the mine. Veins of metal run through me — wrapped in worthless rock. A conventional plant would grind all of us to powder, good and bad alike.
我被破碎了I Am Broken
破碎机把我碎成50mm以下的碎块。有的碎块矿物富集，有的几乎全是废石——从这一刻起，我们的命运开始分岔。 The crusher breaks me below 50 mm. Some of my shards are rich in mineral, some are nearly all waste — from this moment, our fates diverge.
X射线看穿了我们The X-Ray Sees Through Us
在传送带上，X射线逐粒扫描我们的"内心"——按原子密度判定。贫瘠的兄弟被气流击落，去做建材了；我通过了考验。零耗水，零药剂。 On the belt, X-rays scan each of us by atomic density. My barren brothers are shot off the line to become construction aggregate; I pass the test. No water. No reagents.
旋涡中，密度决定命运In the Vortex, Density Is Destiny
我坠入重介质旋流器。硅铁与磁铁矿粉调成的介质里，轻的废石浮出离开，致密的我被甩向精矿之流。吨矿耗水仅0.1m³，全循环。 I plunge into the dense-medium cyclone. In the ferrosilicon-magnetite medium, light waste floats away; dense me is flung into the concentrate stream. Just 0.1 m³ of fully recycled water per tonne.
磨细之后，乘泡而起Ground Fine, I Ride the Bubbles
研磨把我化作微粒。药剂让矿物亲近气泡——我的细粒兄弟们攀上升起的泡沫，聚成金色的精矿泡沫层。此时入选品位已大幅提升2–5倍。 Grinding turns me to fine particles. Reagents make mineral cling to air — my fine brothers ride the bubbles into a golden froth. By now, feed grade has multiplied 2–5×.
我不再是岩石，我是矿产No Longer Rock — I Am Ore
我们汇聚成精矿——而一路上被剔除的废石兄弟，也没有被浪费：它们正变成机制砂、骨料与建材。矿石预选提质，固废循环增效。 We gather as concentrate — and the waste rejected along the way isn't wasted either: it becomes sand, aggregate, building materials. Better ore into the mill. New value from the waste.
