Processing of Bromine

Natural brine is a complicated
salt-water system, containing many ionic compositions in which different ions have close interdependent relationships and which can be
reunited to form many dissolved soluble salts such as sodium chloride, potassium chloride, calcium sulfate, potassium sulfate and other
similar soluble salts. The goal of natural brine processing is to separate and precipitate the soluble salts or ions away from the water.
Due to the differences in the physical and chemical characteristics of brine samples, the processing methods are varied, and can result
in inconsistency of processing and varied technical performance for the different useful components from the natural brine.

Bromine is the first component
extracted during the processing of natural brine. In natural brine, the bromine exists in the form of bromine sodium and bromine magnesium
and other soluble salts.

The bromine production process is as follows:

1.natural brine is pumped from underground through extraction wells by subaqueous pumps;

2.the natural brine then passes through transmission pipelines to storage reservoirs;

3.the natural brine is sent to the bromine refining plant where bromine is extracted
from the natural brine. In neutral or acidic water, the bromine ion is easily oxidized by adding the oxidative of chlorine, which generates
the single bromine away from the brine. Thereafter the extracted single bromine is blown out by forced air, then absorbed by sulfur dioxide
or soda by adding acid, chlorine and sulfur. Extracted bromine is stored in containers of different sizes; and

4.the wastewater from this refining process is then transported by pipeline to brine pans.

Our production feeds include (i) natural brine; (ii) vitriol;
(iii) chlorine; (iv) sulfur; and (v) coal.

Crude Salt

We also produce crude salt, which
is produced from the evaporation of the wastewater after our bromine production process. Once the brine is returned to the surface and
the bromine is removed, the remaining brine is pumped to on-site containing pools and then exposed to
