Before you can get the most out of your mining operation, you need to understand exactly what goes into it. and to truly understand the ores your business is built on takes reliable, dedicated and thorough hydrometallurgical testing. having recently integrated with the autec legacy laboratory, flsmidth now offers the full range of hydrometallurgical testing and mineral processing services. these services include the following.
Pressure oxidation pox is a well-established process for pre-treatment of refractory gold ore and base metal sulfide concentrate. we have batch and continuous pressure oxidation testing equipment available for concept testing, process design or process improvement. we offer testing services suited for pressure oxidation piloting integrated with upstream and downstream unit processes. our technical capabilities include
The dissolution of metals in cyanide or acid may be the most effective method to recover metals from an ore. lab stirred vessels, bottle roll and leach column testing provide criteria needed to design and operate a hydrometallurgical circuit. flsmidth is well equipped to investigate cyanidation of gold ores and concentrates directly or after peroxidation. our hydrometallurgical leaching capabilities include
Autec and its predecessor groups have been studying thiosulfate leaching for many years, and now flsmidth is able to continue testing this technology. in the thiosulfate leach process, thiosulfate is used as an alternative to cyanide, to enable gold recovery from preg-robbing ores. the gold-thiosulfate complex does not adsorb onto carbon as does gold-cyanide, but is instead loaded onto resin, in a resin-in-leach process.
Elution is a multiple-stage process that produces a gold-bearing pregnant solution for electrowinning. loaded resin received from the ril undergoes washing, copper elution, gold elution and resin regeneration. after the gold has been removed from the resin, the barren resin can be reused in the leach.

Placer gold mining mainly refers to mined from the land surface or river or underground. has various types of gold raw material alluvial goldplacer goldsand goldriver gold gold tailing, etc. the placer gold mining equipment includes feeding, washing, sieving, rough separation, final concentrationand refining. because the gold density is much bigger than other minerals, so mainly use gravity separation.
Feeding have various kinds of feeding way, depends on the plant and material conditions . have choices of vibration feeder, hopper, belt feeder, or wheel loader and excavator feed directly. usually will make some grizzly bar on feeding machine or hopper to remove big waste stones. washing this process is to wash clean the clay and mud in raw material, the most popular users are gold trommel scrubber washer and gold washing trommel screen. gold trommel scrubber is for washing raw material that with much sticky clay, trommel screen is for wash raw material that with no sticky clay.
Sieving after washing, need to sieve out some bigger waste material, the under-screen slurry will go to the next machine. this process can use a trommel screen or vibration screen or high-frequency vibration screen.
Primary concentration this process is for rough gold concentration, can use gold centrifugal concentrator or gold jig separator. the concentrated ore from them will go to final concentration machine.
Final concentration the concentrated ore from jig machine or centrifugal will go to gold shaking table for the gold final concentration, can get high purity gold.
Tailing recovery usually will use a gold sluice box to recovery tailings that coming from centrifugal machine. so can get more gold.
Refining if some customer needs very very high purity gold and need to smelt to the gold bar for sale, they can use a gold smelting furnace to smelt gold dust to a gold bar.
The most effective process flowchart and most suitable process types of equipment are always recommended as per the customers request and gold ore conditions and process capacity.

Raw ore processingnbsp after the raw ore ground by jaw crusher and cone crusher, the particles become 30-50mm, put them to concrete directly fine particles need to be produced make the fine particles become the rough particles then transport the mineral by forklift truck to the concrete heap.
The main equipment in heap leaching thatincluding jaw crusher, cone crusher, spray device desorption and electrowinning, smelting device etc. heap leaching is an industrial mining process used to extract precious metals, copper, uranium and other compounds from ores, using a series of chemical reactions to absorb specific minerals and separate them from other soil materials.
Cyanide leaching has been the industry standard for gold processing for more than 100 years. during the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. gold is dissolved by the cyanide and then removed from the heap or columns.

With the rising price of gold and the limited amount of mineable land, people are now focusing onthe recovery of fine gold. some rivers of the world have been sluiced as many as 6 times, yieldingprofitable gold each time and demonstrating that traditional sluices can have very poor recovery.
Gold processing equipment like the igr500 focuses on the recovery of the fine gold.
Gold. in southern africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. while the input material has an average gold content of less than 0.8 gt, the sorted product achieves a concentration of more than 4 gt with an efficiency of approximately 90.
Gold cil carbon in leach process is an efficient design of extracting and recovering gold from its ore. by cyaniding and carbon leaching the gold ore slurry simultaneously, cil process lower the gold mining operation cost, and increase gold recovery rate to a ratio of 98. it has become the first choice of modern gold mining and beneficiation plant design.

It is located in the lapland region of northern finland, approximately 900 kilometres north of helsinki and 150 kilometres north of the arctic circle. with a mine life estimated through 2035, kittila is agnico eagle longest-life mine its proven and probable gold reserves contain 4.4 million ounces 28 million tonnes at 4.80 gt gold.
The mining method at the laiva gold project will include drilling, blasting, loading.
The contract for the supply of mining equipment to the laiva gold project was awarded to metso.
The laiva gold mine is located in finland, approximately 15km south of the town of rahee. discovered in 1980s, the mine is owned by nordic mines and is one of the largest gold deposits in the nordic region based on current reserve estimates.
The mine is currently in the advanced stage of development with all contracts in place to commence production in august 2011. initial production is projected to be 2mtpa, which will yield 115,000oz of gold a year. the mine is expected to be fully operational by early 2012 and achieve target production of 3,700kg of au.
According to a feasibility study completed in march 2010, the mine will be profitable at a gold price of 535oz. nordic mines has already secured 36 of the planned gold production by hedging gold at an average price of 1,049oz until the first quarter of 2015. by doing so, the company has secured the financial and operational costs of the mine.
The mine contains 11.7mt of ore reserves including 5.7mt measured reserves graded at 1.85gt au and 6.2mt indicated reserves grading at 1.88gt au.
The mine lies within the north-western section of the raahe-ladoga suture zone that extends up to 450km in length. structurally, the deposit is complex with various types of intrusive rocks cross cutting the metamorphosed and folded sedimentary rocks and volcanic schist belts.
The area is characterised by proterozoic aged svecofennian rocks of intrusive and volcanic sedimentary origin. the rocks are intruded by granitoid and gabbroic rocks of pre and post organic age. the rock hosted mineralisation occurs within quartz veins and silicified shear zones that range from few centimetres to 10m in width.
The volcanic rocks are primarily mafic uralite porphyrites and include 10 of the mineralised host rocks. the quartz diorite forms the core of the host rock and is large, homogenous and medium grained.
Except in granites, quartz veins are found across all types of rocks. besides quartz, the veins consist of other silicates including arsenopyrite and chalcopyrite.
