There are different classification methods for wastewater treatment, but in principle, it can be divided into three categories: physical treatment, chemical treatment and biological treatment. Each category can be divided into several separation methods. The ore dressing wastewater treatment should be based on the water quality, water quantity and production process characteristics, and consider appropriate treatment technologies from the perspective of energy conservation and comprehensive recovery.
A neutralization method
The neutralization method uses an appropriate neutralizing agent and adjusts the pH to achieve an emission standard or a reuse index for the acidic or alkaline wastewater. And the pH was adjusted to an appropriate range, but also dissolved iron, aluminum, copper, zinc, manganese, cadmium and other metal ions in waste water, a hydroxide precipitate formed was removed. The neutralizing agent commonly used for acidic wastewater is slaked lime and limestone , which are cheap and have a rapid settling speed.
B oxidation method
The oxidation method is a treatment method that decomposes pollutants in water by an oxidation reaction to make them harmless. Commonly used oxidizing agents include active chlorine-based liquid chlorine, sodium hypochlorite, bleaching powder, and hydrogen peroxide, sodium persulfate, and ozone. The ore-containing wastewater containing cyanide wastewater and flotation reagents containing xanthate and sodium sulfide is commonly used in this method. In addition, the aeration method also utilizes oxidation, which obtains sufficient oxygen from the air to oxidize inorganic substances and organic substances in the water, and becomes harmful to be harmless.
In addition to the above two methods, the following measures are commonly used. (l) Increasing the tailings storage volume and increasing the inventory time can not only degrade chemical oxygen-consuming substances, but also reduce the amount of contaminated particles discharged from tailings water. (2) Improve the beneficiation process system and adopt a cyanide-free process to replace highly toxic or toxic agents with low-toxic or non-toxic agents. (3) Improve the return water utilization rate of the concentrator and reduce emissions.
What is the role of an Alligator Shear Machine in metal recycling?
The Alligator Shearing Machine which is commonly used in metal fabrication and scrap metal recycling to cut a range of metal items including pipes, bars, and even profile steel such as I-beams.
Each machine can be controlled manually or automatically.
The Alligator Shear Machine is easy to operate, safe and reliable, and can adapt to a variety of different environments.
How to choose a suitable Alligator Shear Machine?
