The recovery of zinc with this level of CaCO3 is possible however it is economically viable we cannot say. For that truly do the calculations of zinc cleaning process, however as you will not have mining costs but the extraction of the sludge may help us end costs. Another idea is to use this product for CaCO3 as a soil amendment or cement.

The studies on oxide zinc ore indicate a maximum bench scale flotation recovery of 84.5 with zinc grade 24.5 in the presence of dodecylamine at pH 11.5. There are no significant variations in recovery of cationic and anionic and mixed collectors, however, amine and mixed collector flotation show to be more selective than anionic collectors.
method for the recovery of oxidized lead and zinc minerals from ores at present is flota-tion Onal G. et al., 2005. The flotation of oxidized lead and zinc minerals, particularly zinc minerals, is much more difficult than the flotation of corresponding sulfide miner-als. Hexyl and amyl xanthates are capable of collecting smithsonite.

The test had been carried out on a lead oxide ore 18.57 Pb from Kazakhstan, which had a high oxidation ratio above 95 and complexly intergrowed with plenty of alkaline gangue minerals such as calcite and dolomite. A joint flowsheet that combined the gravity separation with flotation was developed to recover the lead, during which flowsheet, a new effective slurry regulator was used.
For a zinc extraction plant in Tibet, there are much slime in the raw ore. According to the zinc ore characteristics, Xinhai adopted pre-desliming, zinc sulfide flotation and zinc oxide flotation process. Finally, the production indexes were stable and the recovery rate of zinc reached 69.56.
Column Flotation is a rapidly emerging technique in the Mining Industry worldwide. This method has been practiced for the passed years and is know as a cost efficient method of extraction with a high productivity level. The recovery of Zinc Oxide using this approach was tested for the first time in Iran at Angourans Mineral Processing Factory.
The recovery of Zinc Oxide using this approach was tested for the first time in Iran at Angou-rans Mineral Processing Factory. The tailing of low grade plants containing a considerable amount of both Zinc and Lead was selected to conduct these tests. The content of Zinc and Lead in the tailing is respectively 18.02 Zn and 3.51 Pb.
The XRF analysis demonstrated that the residue contained 70.3 iron oxide. Based on the sequential leaching experiments, the zinc and lead were excellently depleted from the flotation tailing, leaving a considerable amount of iron in the final residue.
Influence of important factors on flotation of zinc oxide mineral using cationic, anionic and mixed cationicanionic collectors
In recent years, extraction of zinc from low-grade mining tailings of oxidized zinc has been a matter of discussion. This is a material which can be processed by flotation and acid-leaching methods. Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process.
The study aims to recovery of silver minerals from zinc leach residue by flotation method with mixed collectors, namely, ammonium dibutyl dithiophosphate ADD and diethyl dithiocarbamate DD.
