India and Japan signed the agreement on rare earth cooperation



Japanese media said on 28th August, Japan next week will sign an agreement with India, imported about 2000 tons of rare earth from India, in order to strengthen the channels of diversified import rare earths.

Reports said India will export about 2000 tons to 2300 tons of rare earth, equivalent to about 15% of Japanese enterprises annual usage. As early as February next year, India will export the rare earth to japan. Reports also said, Japan has signed agreement with Vietnam, Kazakhstan on a joint development of rare earth resources in the future.

India's prime minister Modi will visit Japan between August 30th and September 3 rd.

Tungsten ore processing plant jig machine

gravity jigging separator


The saw tooth wave jig machine is an effective and energy saving gravity jigging separator device that has found a wide application in recovery for various kinds of minerals. Unlike the traditional jigging machine, The STW jig machine produces speedy upward water flow and slow downward flow, so the bed layer is elevated integrally and settled fully with a long effective loose time. As a result, the STW jig machine has extremely good performance for recovery of fine fraction particles.

JXSC mine machinery produced jig machine is widely used in beneficiation of tungsten, tin, gold, diamond, iron, titanium, iron, manganese, chrome. It can also be used for recovery for alloy particles from manganese slag, chromites slag and stainless slag, etc.

Mine sample testing- JXSC mine machinery factory

                      

For all of mine separator first time need sample testing, our factory have complete sample testing machinery, like lab crusher, lab ball mill, lab shaking table, lab spiral chute, lab flotation, sample separator, vacuum filter and so on.

Gold Mercury Amalgamator in gold refining plant

 Gold Mercury Amalgamator

Gold Mercury Amalgamator is most common used in the alluvial gold/river sand gold/ gold dust extraction processing. It is a traditional way to recovery gold with mercury.

Gold Mercury Amalgamator is a new type of gold, tin purification processing equipment for mix the mercury and gold ore. Amalgamation barrel is a steel cylinder wall lined with rubber, people often put steel ball in the barrel, with the help of steel ball grinding effect can break some gold grains on the surface of dense membrane, have the effect of forcing to mix the mercury and gold.

1. It adopts special motor of vibration motor with excitation source.
2. With Microcomputer time controller can control well the operation.
3. Continuely Full- automatic

4. Good effective for gold extracting and mercury recycling.

Where to Find & Mine Diamonds


When it comes to finding or mining diamonds, there is very little good information available. Geologists who search the world over for new diamond bearing kimberlite deposits are very guarded about what they know. It's all a secret. The majority of placer miners (those who do their mining in gravels and sands) are economically disadvantaged. Africa comes to mind. These miners don't have much planning or purpose in what they do. They simply go to a beach, river or stream where someone has already found a stone or two, and start digging and panning.
If you apply a little thought and perseverance, you will quickly figure out where pockets of placer diamonds are.
I have written this info package to help speed you to diamond locations.
Actually, these precious stones have already been found in our nations rivers and streams. Prospecting gold miners reported quartz-like stones trapped in black sand areas of their sluice boxes..... and threw them back in the waterway in which they were working. They didn't know a diamond from a quartz rock. Or that those small garnets in their gold pan could be indicator minerals of diamond bearing kimberlite pipes. No one had educated them on what to look for, or how to track back on waterways to the rich source of wealth these transparent stones meant.
The information in the diamond mining package covers placer mining for diamonds.

Lead ore concentration machine, Lead mining equipment, Lead ore jig separator


The composition of galena is PbS with its good floatability and specific gravity of 7.4-7.6. So the beneficiation of galena lead ore is froth flotation separation and gravity separation. Flotation separation makes use of its floatability to get high grade galena concentrate. Flotation beneficiation processing can help to get high enrichment efficiency, but it requires much about the operator with its high plant investment and high operation cost. However, flotation separation can be unfriendly to environment and it has been limited by government, and it will be taken place by gravity separation. Gravity separation has a low requirement about the operator with its small plant investment, and low operation cost. With reasonable plant allocation, the beneficiation efficiency of gravity separation is even better than flotation separation. So galena lead ore gravity upgrading will be the leading beneficiation method instead of flotation separation.
Galena gravity upgrading works greatly to gain high grade galena lead concentrate on basis of big specific gravity difference between galena and its gangue. The crude galena is crushed and screened to make the galena granules liberated from its gangue. Kind of gravity separators like jigging machine can be used to purify the galena to get galena concentrate and tailings. Machines like crushers, rod mills, jig separator, shaking tables can be involved in galena gravity processing flow sheet. The simple crushing breaks the big blocks into small ones while rod mill, as kind of milling equipment, is used to mill the crushed output to be fine of -5mm without any extensive-milling. Galena lead jig machine can be involved to enrich the milled galena to get the final concentrate and tailings. There shall be some fine granules in the tailings from jigger, so a shaking table can be used to recover the galena in the tailings to improve the recovery.

JXSC is a manufacturer of kinds of mining machines for beneficiation of placer gold, quartz gold, mercury, barite, fluorite, celestite, pyrite, hematite, manganese, and recovering of smelting alloy from smelting slag of silica-manganese smelting slag, chromite smelting slag, and ferro-nickel smelting slag. Free test can be done for you if samples of 10-20 kg can be available.

Gold Beneficiation Overview

 cone crusher

According the structure of mineral status of gold, the gold mineral can be divided into three categories, the gold mineral gold deposits, gold-bearing minerals and gold minerals contained. The so-called independent gold mineral, refers to gold and gold-bearing minerals in the form of the mineral output of gold, it is the nature of the most important occurrence in the form of gold, the main target of industrial development and utilization.

The current mainstream technology for gold beneficiation, usually by crushing by crusher, then grinding by ball mill, and get the concentrate or tailing by gravity concentrate plant or flotation concentrate plant, finally through chemical method and smelting to get the product gold.


The first part is crushing and grinding, most use jaw crusher to crushing the raw ore, or use cone crusher to get small size ore, most of small or middle plant will choose 2 crushing parts rule as more crusher less grinding to get fine particle size. The second part is gravity concentrate plant, the gravity beneficiation concentrate according different density of different minerals, it’s the main important method for gold recovery. Most equipment as sluice, shaking table, jig separator and centrifugal concentrator etc. The third part is flotation concentrate plant. In China there is more than 80% gold beneficiation plant choose the flotation machine to recover gold. The product after flotation will deliver to smelting factory process. Except those method, also have mixing mercury, cyanide, leaching and melting. Our factory is professional in gravity concentrate plant, the gravity concentrate plant with less cost, high capacity, easy operation features. Our equipment is used on many gold mine areas in the world, we can supply different gravity equipment, like as gold shaking table, sluice box, gold centrifugal concentrator, jig separator etc.
