reduction of flocculant used on the tailings thickening process of Neves Corvo Mine. The dosage and concentration of three different flocculants is modified and the effect on settling measured. During a 4 months internship on the company, settling tests were carried out, using several combinations of the
Flocculants are used in the mining industry to treat the water used in mineral extraction and flotation processes. They help aggregate fine suspended particles to form larger flocs so that the solids can more easily be separated from the water. Flocculants are used to clean flotation process water to reduce reagent consumption and improve recovery.
Flocculants The main large copper mining companies use imported flocculants, different commercial brands are available. The main manufacturers are SNF, Basf, Kemira and Orica. The suitable flocculants are chosen based on lab test results, therefore, it is unlikely for an immediate switch to a different brand.
The flocculant used was a commercial anionic polyacrylamide, SNF 704 supplied by courtesy of SNF Chile S.A., with a molecular weight higher than 18 10 6 g/mol. A 2.5 g/dm 3 polymer solution (0.25 wt.%), gently mixed for 24 h, was prepared and used before two weeks after preparation to minimise ageing effects.
Jun 16, 2017 Simple systems with constant feed can use flocculant pump speed control, more advanced control systems utilize a ratio controller to maintain a constant grams per ton dose rate. Unfortunately, fluctuations in ore type can significantly change the dosage of flocculant required and require a feedback to the grams per ton constant.
By 2015 DRC and Zambia will be the 3rd and 4th largest copper producing nations behind Chile and Peru. Kemiras Superfloc brand of dry flocculants, has found application in copper mining for many years. Thanks to their effective application, Kemira is now the leading flocculant supplier to
In copper mining, it used as thickener agent, flocculant agent for flocculation and sedimentation, quick liquid and solid separation, low dosage and low cost. Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine.
anionic flocculant DRYFLOC SU 13 E A DT For this copper mine, saving water is a day to day challenge as it operates in a desert environment. The use of DRYFLOC P leads to the production of a higher underflow solid concentration which remains pumpable. This returns more water to the process immediately, reduces the evaporative losses at
Oct 30, 2018 Bront 234 and APAM D8625-10 are anionic flocculants and have an amide group on the polyacrylamide. They were all received in powder form and were prepared using the same procedure. Table 3 gives the physical properties of the flocculants used. The flocculants were dissolved in deionized water for a final concentration of 0.1% (w/w).
Flocculants for copper, lead and zinc mining. Copper, lead and zinc are mined underground using large industrial machinery. After the ore is crushed, it is then brought to the surface. A flotation process is necessary to separate the metal from the waste. 3F Chimicas flocculants
