使用淘金厂,裸露的含金砾石使用推土机开采,推土机将砾石推到洗选厂附近堆放。堆存的含金砾石随后由前端装载机或大型反铲送入洗选厂。这种做法通过允许推土机继续采矿,同时装载机或反铲以稳定的速度向洗选设备提供饲料,从而提高了设备效率。当开采的砾石被送入洗车厂. 使用各种固定式或振动筛按粒度分类。对砾石进行分类可以更有效地回收黄金,降低耗水量,并促进矿区恢复,大多数操作人员都采用这种方法。过大的材料,通常大于两英寸,滑出洗车厂进入一堆,它可以移动的前端装载机或推土机。尺寸过小的材料和含金砾石与水混合,并流经集金和重黑砂于一体的浆箱。尾矿是堆积在水槽末端的砾石、沙子和其他物质。尾矿通常由装载机或推土机运走。

载着含金砾石的水通过浆箱,变得含沙和浑浊。这种“浑浊”的工艺水从浆箱的末端流过一堆新鲜尾矿,进入一系列沉淀池。这些池塘的设计是为了保持“浑水”足够长的时间,使细泥沙沉淀下来。池塘的物理设计取决于流经系统的水量、正在加工的砾石的沉积特性和场地的物理特性。大多数矿山使用一系列小型沉淀池,以便更灵活地进行水管理。小型池塘通常比大型池塘更容易建造、维修、清理、更换、绕道和修复。鼓励使用预沉池。预沉池位于水闸和第一个沉淀池之间的尾水渠中。沙子和其他重的可沉降固体被收集在这里,它们很容易清洗。

然而,一些零排放系统确实偶尔有排放,通常是由于通过池塘堤坝的渗水。这种渗漏几乎总是符合可沉淀固体的排放标准,而且在大多数情况下,可能比通常运行的沉淀池排放的水质量更好。一、 即,可沉降固体少,浊度低。为了实现“浑水”零排放到相邻河流中,需要精心设计和实施水管理实践。冲洗过程中所用的水是从附近的溪流中泵出,通过洗车厂进入沉淀池。当池塘中含有足够的水,通过将池塘水循环到河流中来支持持续的冲洗作业时,溪流的取水口被暂停洗车厂. In some cases, groundwater seepage Into the settling ponds may be sufficient to eliminate the need for adding stream water to the system. The practice of zero discharge and the recycling of mine water contributes to compliance with federal effluent limitations and State water quality standards.

砂矿开采涉及的设备从一个简单的金盆一直到卡车,挖掘机,和一个大的淘金厂这类型的黄金勘探通常涉及勒ss investment and will consistently yield small amounts of gold, with occasional bonanzas for those who are persistent. If you can learn to reliably return from every trip with decent concentrates, so that over time you fill a five-gallon bucket, and then maybe even a fifty-five-gallon drum, with black sands, magnetite, ilmenite, rare earth elements (REEs), and gold, you will be rewarded in the long run.

Either way, your long-term goals are your own.Very few prospectors are simply in it for the money, looking at this as a way to become a millionaire overnight. Some of us just like to get out of town, camp in the mountains, and enjoy the spirit of the outdoors. Some people like to work up a little sweat and appetite, improve their health, and learn a little. Some of us like to solve problems and run machinery, and enjoy the challenge of keeping a pump going or making sure the sluice is running right. Still others like the wildlife, the scenery, and the historical importance of the Wild West, and bring back their riches as photos and videos. In each case, if you toss in a little gold fever as motivation and stay scientific about your sampling and exploration, you will prosper far and above the value of your recovered material.

不过,好的发薪日总是一种享受。实现这个目标的一个可靠方法就是不断尝试。不断练习,不断探索,不断走出去。另一个似乎成立的真理是,离文明越远。你的机会就越大。

如何开始砂矿开采

启动自己的装载/放置矿的指南

The development of a load/placer mine and the selection of the proper gravity recovery plant is more difficult than most people realize. Television shows have glamorized mining making it look like anybody can start a mine with little to no experience. What people don’t realize is that mining is a structured engineering discipline taught at university. Just as you should not build your own bridge with out knowledge of civil engineering, you should not think becoming a miner is a simple task. If you have no experience in the mining field you need to get educated about the process before you embark on this adventure. We have compiled a basic guide to assist in that process.

The terminology used for this type of mining is often interchanged. The term for the type of deposit under consideration is alluvial. Alluvial deposits are formed when the gold has migrated from its original deposition by weathering to a new locations often in active stream beds or in historic water courses now overlain by sediments or glacial sediments.

一般来说,砂矿开采通常是通过使用挖泥船和水闸或其他重力方法从河流沉积物中回收黄金。负载开采通常涉及剥离上覆层(土壤),以揭露含有黄金的下伏砾石。这些矿床通常用移动设备开采,矿石用卡车运到重力处理厂。

Developing A Mine

需要考虑的事项:

1Permitting–允许我干扰土地–挖掘坑、留下尾矿、用水、噪音、空气质量。在大多数情况下,即使没有适当的许可证,你也不能简单地在自己的土地上开始采矿。

2资源量估算-存在多少黄金(品位和吨位)以及矿床的外观-超负荷深度、矿石深度、砾石尺寸。通常,砂矿资源是通过在矿床周围钻孔或螺旋钻来确定金矿的范围。这通常与现场重力回收试验相结合,以提供可采品位的估计值。

三。Ore Characteristics–材料是否易于处理或是否存在大卵石,材料是否粘土含量高,材料是否冻结。

4.试验工作– have you conducted any test work or field testing. A gravity recoverable gold test is an important piece of information that allow you to understand how much gold can be recovered.

5.用水–重力系统使用大量的水,但大部分水可以通过适当的计划回收。你需要合适的数量来开始操作。

6.Mine plan–您是否有开采计划–您将首先在哪里开采,覆盖层将放置在哪里,尾矿将放置在哪里,工厂将位于一个地点还是在矿山寿命期间移动,运输距离是多少。这是季节性手术吗?

7植物选择–有多种清洗设备可供选择,选择合适的设备需要对情况进行分析,以确保选择正确的设备。

矿山条件
– Where is your project located? – terrain, climate, infrastructure variables
–你们的让步有多大?移动设备或固定设备是否适合此应用?
– How many yards/hour (m³/hr or tons per hour) do you want to process?
– How much water do you have available (gpm or m³/hr)?
– Is there power available from the grid or do you required generation?

Plant Characteristics
– Are you looking for a mobile machine that you move regularly or a stationary plant that you haul your ore to?
–您将为工厂提供何种类型/尺寸的设备(前端装载机、挖泥泵、其他)?

Feed Characteristics
– Ore consistency:
– What is the estimated maximum boulder size (in, mm)?
–是否存在明显的粘土?
– What is your maximum gold size (mm or um)?
–是否有纯金,典型尺寸(um)是多少?

8经济模型–一旦你做了一些初步的假设,你就需要建立一个经济模型(甚至是一个基本的模型),这样你就可以在开始之前知道这个项目是否可行。无论是什么类型的项目,你应该尝试建立一些基本的经济,除非这只是一个小爱好的运作,利润并不重要。开发模型需要很多假设,你需要在评估中实事求是。运营成本增加10-15%或有费用,资本成本增加20-30%。

  • Revenue – how much gold can be recovered
    o每期处理吨位
    o回收品位
    o黄金价格
  • 运营成本-回收这些黄金需要多少成本
    o Mining Costs – over burden stripping, excavation, haulage, dewatering, labor, lease or buy
    o加工成本-工厂备件、劳动力、水、发电
    o营地成本s – travel, lodging, food
    o黄金运输、安全、精炼和保险成本
    o G&A成本-许可、主管、法律
    o Concession Costs – purchase price or lease fees
    o Royalties – third-party payments to property owners or governments
  • 资本成本-需要购买哪些设备才能使项目成功
    o Mining Equipment – dredge, excavators, bulldozers, haul trucks, front end loaders
    o工艺设备-哪种工厂适合生产能力和矿石特性
    o辅助设备-水泵、发电、轻型车辆
    o营地成本
  • 现金流-根据上述项目制定年度现金流,并确定税前净现值和内部收益率。下一步不要忘了税收,还要考虑汇率和国外项目的利润返还。
  • 优化——一旦你完成了基本模型,你就应该通过它来看看你如何才能最大化你的利润——调整吨位(这会改变资本和运营成本),调整截止品位——不要为了黄金生产(休闲采矿)而交易美元——如果它不赚钱,就把它抛在脑后,如果你可以的话,考虑运输距离和移动设备…。
