钾盐矿山开采方法

农业假肥是怎么开采和加工的？这是一个位于加拿大的假洋矿，假洋矿一般藏在地下八百米深的岩层下方，矿坑中主要含有三种物质， 分别是绿化甲、黏土和绿化那，后者是制作食盐的主要成分。为了将这些矿石运送到地面，工人们操控的大型的采矿机械来切割岩壁，旋转的机器上各有三只手臂，每只手臂上都装有六对碳化物。钻石 刮下来的碎矿会进入机器内部进行输送，这个矿场有十台这样的机器同时作业，他们采挖得来的碎矿全部通往一条长达三十五公里的主输送带，上 带有输送带末端的一台电梯，一次将重达四十九吨的矿石运送往地面，并将其倒入库存桶内。地面上的输送带会接过活儿将矿石输送到加工厂。假烟矿首先会经过一 一系列的震动筛，使较小的颗粒从筛眼震落，直接转入下一站，而较大的颗粒则会顺着盐水流进破碎机里粉碎。直到所有的假硬矿都变成统一的大小后，接下来要做的是将假肥夫选出来，工人们往夫选槽内加入十八啊夫选剂。 经过五分钟的化学处理，绿化甲颗粒会与浮血剂产生的气泡结合，气泡的密度小于其他的物质，所以气泡会往上浮， 这时候上面的滑板再将浮起来了。绿化甲推入到一旁的收集头，而黏土与绿化那粒子则会被立到另一端， 这样得到的就是高纯度的假肥，也就是绿化甲。之后绿化甲进入离心机和干燥机，去除所有的水分，再进入震动筛选机，将其分成三种规格，较大的颗粒需要回到破碎机碎成小粒，尺寸过小的则进入机器压缩成板状，然 然后把它打碎成新的颗粒，再回到震动筛选机进行另一轮的筛选。重复筛选出的成品会直接送入到出锅仓储得到。这种颗粒状钾盐就是用做农业肥料的钾肥，它的绿化钾浓度是百分之九十五，里面仍然含有一些残留的粘土以及绿化呢。 技术人员会定期抽取样品进行测试，检测绿化甲的准确含量。如果想要将绿化甲纯化到用作工业用途，它的浓度就必须达到百分之九十九。因此，工厂需要把纯化到百分之九十五的绿化甲放入到热炉水中， 继续去除更多残留的黏土和绿化呢？经过冷却后吸出绿化钾结晶，再经分离、洗涤和干燥，最终得到的几乎就是纯净的绿化钾了。

potash is potassium chloride a compound with the chemical composition kcl， it can be processed into a granular agricultural fertilizer or into a higher grade product for industrial use at this canadian potash mine， the or deposits lie， a kilometer underground， the or is comprised of three potassium chloride clay and sodium chloride that's an own assault a machine known as a continuous minor is used to cut into the rock face it has two rotors each with three arms each arm has six pairs of bits tipped with ultra strong carbide that bite into the rock and flake off the air the rotar arms sweep the or into the machine which feeds it through a series of conveyor belts sheets of polymer fastened to the rock above direct the flow of fresh air that's pumped down into the mine to help ventilate it the ore is gradually transferred away from the rock face by the network of conveyors at this potash mine ten machines work simultaneously at different locations their conveyors which total 35 kilometers of moving belts converge at the skip a giant elevator bucket， which hoists up 45 tons of orator time to the surface and dumps it into a storage bin another conveyor now transfers the auto the mill for processing at the mill the all first tumbles down a series of vibrating screens smaller particles drop through the openings and move on to the next station， while larger particles stay on top where a flow of brine washes them into a crusher the finest particles flow to the fine flotation tank， while the larger one sink to the bottom before draining out and traveling to the course flotation tank both sets of particles are now treated with chemicals over five minutes the chemical treatment makes the potassium chloride particles attach to air bumbles and rise to the surface in the course flotation tank paddles skim the surface pushing the floating potassium chloride into a collector the clay and salt particles are drained from the other end of the tank similarly in the fine flotation unit， the potassium chloride particles attach to air bubbles and rise to the top where they overflow into a collector the potash that's been collected then passes through a centrifuge and a dryer to remove any moisture the dryer feeds a vibrating screening machine which separates the potassium chloride particles into three categories oversized particles are sent back to the crusher undersized particles are sent to machines which compact them into boards before breaking the boards into new particles which is sent back to the vibrating machine for another round of screening particles of the correct size for the final product a transferred to the shipping warehouse this granular potash will be used as agricultural fertilizer it's comprised of 95 percent potassium chloride along with some residual clay and salt samples are regularly tested to confirm the potassium chloride content to do this each sample is ground into a fine powder and compressed inside a stainless steel cap to form a pellet the pellet is then loaded into an x ray fluorescent analyzer the sample first absorbs energy and then releases it as fluorescent radiation the analyzer measures this fluorescence to determine the samples concentration of potassium chloride the mill also processes potash for industrial use this higher grade potash with a potassium chloride concentration of 99 percent is a white powder this is made by dissolving the granular 95 percent potassium chloride in hot brine to remove more of the residual salt and clay the potash is then crystallized by evaporation and cooling to leave potash that's almost pure potassium chloride it's fair to say a little more sophisticated than horsemock。
