从本质上面，金挖掘机基本上是相同的方法，涉及在手工采矿的情况下涉及泥浆的筛查和紧张，提取过程通常需要更长的时间，因为它涉及低科技设备和体力劳动
The lifecycle of a gold mine people in hard hats working underground is what often comes to mind when thinking about how gold is mined yet mining the ore is just one stage in a long and complex gold mining process long before any gold can be extracted significant exploration and development needs to take place both to determine as accurately as possible the size of the deposit as well
采矿过程5浸出和吸附浆料的碎片矿石水和弱氰化物溶液进入大型钢渗漏，其中金和银溶解在该浸出过程中，浆料通过六个吸附槽，含有碳颗粒的吸附罐。
A process for treating a particulated gold bearing ore to recover the gold therein is disclosed the process includes roasting the ore to remove sulfides as sulfur dioxide followed by chlorination of the ore at a temperature of about 350 c in the presence of iron to form a mixture of volatile gold chlorides and volatile goldiron chlorides in the chlorine off gases followed by condensing
Gold extraction as a tool they also finetuned each step of the process from crushed ore to gold pellet their method is as follows the first step after crushing the ore is milling this takes place in metal drums with hard metal rods or balls no mercury is added after milling the groundup ore is
来自矿石和电子废物的黄金的提取是全球范围内的重要主题，因为这种贵金属在各种领域具有巨大的价值，然而由于使用有毒氧化试剂和苛刻的反应条件导致的严重环境污染和高能耗是众所周知的问题在金产业中
为了最大化黄金提取汞通常用来与金属合并金属，通过煮沸汞汞汞的汞产生的金属是有效的，在提取非常小的金颗粒，但由于汞蒸汽的毒性，该过程是危险的
2014年10月20日浸出金色含有氰化物溶液仍然是最广泛使用的液态冶金工艺，用于从矿石中提取金子，尽管使用氰化物的困难和危害，但尚未被证明是经济可行的替代方案
2012年1月23日在近代，虽然矿业为黄金是一个更加密集的，但是，大多数表面或冲积金都已发现，这就是为什么黄金主要从地球开采它的主要原因，这是一种技术问题，需要大量专业知识和精心设计的设备今天的黄金矿业可以基本上被分成9个步骤
从地面上删除金色的岩石只是孤立的纯金矿业公司使用复杂的提取过程的第一步，这一过程的第一步是将大块岩石沿着较小的碎片，以磨机为较小的机器，称为破碎机减少矿石至
黄金的实际采矿只是金矿过程的一步，了解金的开采方式以及大规模金矿项目的五个阶段
