The fate of the ferrous ion (Fe2+) depends on condensate temperature, pH, and flow conditions. At low temperatures, Fe 2+ reacts with water to form insoluble ferrous hydroxide, Fe(OH) 2.If the condensate stream velocity is high enough, colloidal Fe(OH) 2 is swept into the water and car-ried downstream to deposit elsewhere. In low-flow areas of the …
Nickel sulfate. Nickel sulfate is the source of most of the nickel ions and is generally maintained in the range of 20-40 oz/gal (150-300 g/L). It is the least expensive nickel salt, and the sulfate anion has little effect on deposit properties.
Potash Corp. is the largest producer with 5 mines in Saskatchewan and one in New Brunswick, Canada. Potash is also being extracted from the waters of the Dead Sea. While gypsum deposits are found all over the world, the United States is the largest producer of gypsum, followed by Iran and Canada. Salt (halite) deposits are also found …
In this study, we determined the solubility of Th dioxide (ThO 2) in aqueous solutions as a function of sulfate concentration from 0.05 to 0.5 m Na 2 SO 4 at temperatures between 175 and 250 °C ...
Deposit Selection and Preparation. Six model deposits (Table 1) were selected to systematically compare the role of the anion makeup (just oxides, just sulfates, or mixtures of oxides and sulfates) and the presence or absence of Na and K salts.These compositions are based on a master cation stoichiometry C 13 N 10 K 1 M 11 F 11 A 14 S …
Calcium Sulfate is a critical component in the measurement of permanent water hardness (also known as non-carbonate hardness). This part of water hardness is defined by the sum of all calcium and magnesium ions that are associated with anions such as chloride or sulfate. It is referred to as permanent hardness because of the fact that it will ...

Many non-cyanide copper processes operate between 54–65°C (130–150°F) with air agitation. A typical bath formulation contains 11g/L of copper metal. The pH is around 9.0, while cyanide copper solutions have a pH of at least 11.0. The anode-to-cathode ratio is 2:1, with the same anodes used in cyanide copper solutions.

In only a few deposits do soluble sulfate salts occur with the potash, such as zones of the Zechstein Basin where "hartsalz" (sylvite with kieserite, MgSO 4 · H 2 O, or anhydrite and halite) is common; double salts such as zones in Sicily and Ethiopia where kainite (KCl · MgSO 4 · 2.75H 2 O) is predominant; and in areas of Carlsbad, New ...

Mining of native sulfur deposits is accomplished by the Frasch process, which uses superheated water to melt the sulfur so that it can be pumped to the surface. Sulfur is used in petroleum refining and in the preparation of fertilizer and chemicals. Texas is one of the nation's leading producers of sulfur.

Waterfloods combining ground waters with high calcium and high sulfate contents can deposit anhydrite or gypsum by much the same "incompatible waters" mechanism discussed for barite. However, calcium sulfate scale solubility, unlike that of barite scale, actually increases with decreasing temperature (until about 40°C).
