What is the gold crushing process flow? how to extract gold from its ore? In the paper, I make details from the gold crushing circuit, crushing equipment, primary crusher, secondary crusher and tertiary crusher, screening. Join us.

Every gram of gold from the stones is indispensable to experience mining crushing grinding sorting smelting casting, etc., from the perspective of mineral processing, the crushing is the first mineral beneficiation process step, and it is almost a preparatory section for any gold processing plant. By crushing process, reduce the large ore to ideal particle size for grinding.

The gold crushing process design is determined by the ore amount, hardness and the crushing ratio. The most commonly used rock crushers are jaw crushers and cone crushers; in addition, vibrating screens (round vibrating screens) are required to complete the closed circuit with the crushers.

Jaw crusher is generally used as the primary crusher in the crushing circuit and connects to the ore feeding machine. In the early years, common used plate feeder, but now, the vibrating feeder is more popular. Practice has proved that the vibrating feeder has advantages of low power consumption, strong transportation capacity, low failure rate and easy maintenance, which can fully meet the needs of both of large scale gold plant ore small scale processing plant.

For medium hardness ore, the ore can be gradually crushed from the crusher mouth. For the ore with higher hardness, the material may be broken in the middle of the jaw plate, so that the opening width of the crusher mouth needs to be wider.

Each crusher has a maximum feed size, which surely is not a fixed value. For medium hardness ore, adopt extrusion type feeding mode, even if there is a small amount of large ore exceeding the maximum feed size, has no effect on the work of the crusher. On the contrary, if the material is high hardness ore, it is better to intermittently feed to avoid clogging.

In addition to the maximum feed size, an important parameter of the crusher is the discharge gap. The discharge gap is not equal to the maximum discharge size. The maximum discharge size of the jaw crusher is usually 1.5-1.8 times of the discharge gap. Each crusher has a minimum discharge clearance. In order to ensure the stability of the crushing process, 1.5-2 times the minimum clearance is selected to complete the first stage of the fracture.

The iron is fatal to the cone crusher, so the ore must be removed before enters the cone breaks. An iron remover (in fact, a magnet) can be added to the upper part of the belt conveyor to preclude the wire, nails, welding heads and the like.

For the cone crusher, it is must use the extrusion feeding method, intermittent feeding method damages the equipment very much. Therefore, professional cone crusher manufacturers will configure a small buffer tank for the cone crusher. The material from the fine crushing bin can be fed into the buffer tank through a belt feeder or a small vibrating feeder. If use a chute, you can remove the buffer and let the material accumulate directly in the chute.

Similarly, the cone crusher also has the maximum feed size. This parameter value is a mandatory parameter. Never try to exceed it. Once it is stuck due to excessive material, it is very troublesome for the cone crusher.

It should be noted that, due to the closed-circuit crushing formed by the vibrating screen, the cone crusher is not the larger the discharge gap, larger the processing capacity. Different discharge gap determine the different qualified product rates and the ore recrushing rates.

As the gap increases, the actual processing capacity of the crusher increases, the gap becomes smaller, and the speed of the crushing decreases. Both of these two conditions are harmful in production. We should find the best gap in the commissioning to make the production smoother.

As the vertebral body wears, the gap will increase accordingly. In addition, the maximum discharge size of the cone crusher will reach 2-3 times of the discharge gap, so the gap size can be judged according to the granularity of the discharge during the adjustment. Never blindly adjust without a clue.

Screen layer Generally speaking, small scale gold plant use single-layer screen, medium and large mines use double-layer screen, but the purpose of double-layer screens is not to grade three products, but to improve screening efficiency.

Material As for the choice of materials for the screen, it depends on the users usage habits. It is certain that the polyurethane (rubber) screen has a longer service life, a lower screening efficiency, and a steel-wire mesh that is more fragile, but has a higher screening efficiency and is easier to maintain.

Due to the relatively harsh environment of the crushing operation, the single shift time is less than 6 hours. Therefore, when selecting the gold crushing machine, the working time is generally determined by two shifts of 6 hours or three shifts of 5 hours.

An Easier Way to Crush Rocks! Once primarily used by landscapers and contractors to crush rock for demolition, gold miners are now using them to both test material in the field, and recover gold back at home. In most cases, you can take your rock crusher straight from the shipping container and use it in less than half an hour. No wasted time trying to find the right pulleys or chains. Whether you need a manual rock crusher or a motorized version, you get everything you need to start crushing / pulverizing rock and getting the gold right away! A rock crusher can be an invaluable tool if it has been designed and built by miners for miners just like you'll find below. Tough machines built well and rigorously tested in the field means less work for you. Warranted by the manufacturers.

During the rush to the gold fields of the 1800s, a LOT of gold was removed from the rivers and banks of the Western US and Alaska. The old-timers used very ineffective methods, but a lot of gold was taken out of the streams and banks. That gold had been setting there for hundreds if not thousands of years. It takes time for the waterways and banks to "replenish" the gold that is recovered by miners. Mother Nature helps every year through floods and snowmelt.

Keep in mind that all the gold in any river came from "above" -- from the veins and outcrops that push up through the hillside and slowly, due to weathering (freezing and thawing, wind and rain) a chunk of gold bearing quartz is eventually broken off and tumbles downhill until it finds its way into the river where it is warn and shaped even more by the action of the water, sand, etc. Every time gold moves in the river, it goes deeper down, until it hits bedrock, and there the gold sits until it is found.

Over millions of years, the Earth has gone through many changes. Sometimes, a river that is laden in gold will be thrust up and dry out. That is why you may find placer gold high up in an exposed rock bed with obvious water-warn rock. Sometimes the river changes courses, and new rivers cut across the old channels. No matter how things change, the fact remains that the gold came from a vein, which eventually became an outcrop. Knowing this, many modern-day prospectors are switching from working barren streams to hard rock, and hunting for those outcrops with could lead to a very valuable vein. Even if you do not work it yourself, you may have a good discovery which could mean another person or company will buy or lease your find!

Rocks are rocks, unless they contain valuable minerals, metals, or elements. When a rock has values in it, it's then called ore. In order to liberate the minerals, it needs to be crushed down. In days of yore, a stamp mill was the primary form of crushing rock, but in the modern world, there are jaw crushers, impact mills and gyrator crushers, as well as ball mills. They all have their own pros and cons -- and price tags. Crushers take larger rock and break them down to smaller rocks, and then they are processed through an impact mill to reduce the ores to a finer particle. If the ore needs to be smaller yet, it's placed in a ball mill to reduce the materials to a slurry that has the consistency of muddy water.

Some mining companies have very large equipment, which can handle hundreds of tons or rock an hour. These businesses can effectively go after ores of lower grade materials because of the high volume they can process. For the average prospector, though, it's not feasible to crush down a ton of ore for only a few grams of gold. The average miner can instead purchase a CrazyCrusher manual rock crusher or an electric or gas powered rock crusher and get the gold out in smaller batches. Crushing rock to recover gold can be easier, faster, and much more profitable than prospecting in over-worked streams and rivers. With prices starting at less than $500 for a manual crusher, you may want to consider this time-saving method for getting the gold!

Most gold ore crushing equipment isconstructed of a welded or cast exoskeleton framework that relieson bolt in liners to protect the machine. Over time, the framework begins to lose shape frommetal fatigue and overrunning of liners. Soon the machine is stretchedout of tolerance, resulting in excessivemaintenancerequirements and your machine never quite runs as it did when it was new.

The Goldbelt Global OLESI line of crushers incorporates the wear components into the body of the machineto form thestructure. All components are bolt on and nearly weld free. This means every timeyou order a new set of liners, your machine is returned to factory specification. For those in remote areasthis machine can be completelyrebuilt with a set of wrenches.
