Treatment Of Non Ferrous Metal Ores Associated Gold

551 words - 3 pages

Non-ferrous metal ores often associated amount of gold . So choose a suitable crusher is very
important, there are many kinds of crusher , crusher and some students can provide
information to guide manufacturers , such as jaw crusher manufacturers in india these payments are usually

included in the order Cu, Pb, Zn based multi- metal ore , copper and copper-nickel-ore. Gold

grade is not high , generally no more than 2 g/t . However, due to the large -scale non-

ferrous metal ore deposit , ore mining capacity, so the associated gold production account

for a large proportion of the total production of gold . Some important gold-producing

countries such as the United States each year , 40% of gold production from Cu, Pb, Zn, Ni

byproduct of the former Soviet Union is 20% to 30%, in Japan 65 % of the ...view middle of the document...

Others need to provide certain

conditions , or require the use of specialized tools can be recovered gold extraction , so

this part of the study associated gold recovery , you should first consider the output of

non-ferrous mineral products as qualified as possible while gold enrichment to the non-

ferrous metal ore products, or other specialized enrichment to the amalgamation of gold

operations products.

    For treatment with a small amount of gold polymetallic ores , the key is to grasp the
gold in the ore occurrence , symbiotic relationship with a variety of mineral deposits , and
as a basis for the development of rational processes with gold , select the appropriate
processing equipment, has when can consider using the Small Gold Mining Rock Crusher for Sale which is Professional gold mining

equipment. When the gold in the ore mainly in the form of free gold output should be used or

re-election amalgamation gold recovery process . When gold is closely related with a certain

kind of symbiotic mineral , can be selective flotation process , the gold enrichment to each

product concentrates for smelting recovery .

    When polymetallic gold ore flotation , master inhibitor dosage is very important. For
example, in native gold copper ore , generally contain pyrite. In order to suppress the iron
float copper , the use of lime as inhibitors. Because lime gold also inhibited , so when
there is a floating copper, must master the amount in the range of lime . This can not only
avoid the loss of gold with pyrite from the tailings , and also be able to choose a high -
grade copper concentrate . If pyrite sulfur concentrate as a separate output , then the
separation process in copper sulfur , lime dosage can be adjusted within a large range.
Because sulfur concentrate into gold , can be recovered at a later cyanidation process or
smelting process .
