Limonite

Limonite ore containing water of crystallization is Fe 2 O 3, the formula can be used mFe 2 O 3 · nH 2 O represents, it is actually a goethite (mFe 2 O 3 · nH 2 O), water hematite (2Fe 2 O 3 ·nH 2 O), a mixture of iron hydroxide and mud. Most of the limonite in nature exists in the form of 2Fe 2 O 3 ·nH 2 O.
The density of limonite is 3.0~4.2g/cm 3 and the hardness is 1~4. Its appearance color is yellowish brown and black, and it is non-magnetic. Since the limonite ore is formed by weathering of other ores, the structure is soft and the water content is large.
In the natural world, limonite is less rich in ore, generally containing 37% to 55% of iron. Its main gangue is clay and quartz , and sulfur, phosphorus and arsenic are generally higher. When the iron content is less than 35%, it needs to be beneficiated , usually by re-election method and magnetization roasting-magnetic separation method.
At present, some pellet plants, such as the Robe River in Australia and the Sidor plant in Venezuela, have become the main raw materials. China's Pingxiang Iron and Steel Plant also uses some limonite to make balls.

Pool Heat Exchanger

A Special high flow pool heat exchanger should be used instead. These heat exchangers can handle the higher secondary side flow as well as the high levels of chlorine and also have better flow characteristics making them ideal for solar pool heating or solar hot tub heating. For applications that use salt water, we recommend the Titanium version of the pool heat exchanger. This version is highly resistant to salt water and chlorine.

Our Pool Exchanger Line of heat exchangers are designed to perform at high secondary side fluid velocities with low pressure drops.

Features:
With high heat transferring efficient heat exchanger tubes and smooth shell, it ensures high velocities inside of the unit making the heat exchanger a very reliable, efficient and cost effective way to transfer heat indirectly between any solar heating or boiler circuit and any pool or spa circuit, besides other applications.
Advantages:
•High efficiency, coefficient up to 14000 w/m2 deg C, Heat exchanging capacity 3-7 times traditional equipment`s
•Compact configuration, occupy small area, one tenth as the traditional equipment
•Stainless steel and/or Titanium, material, endure high temperature, pressure and corrosion
•Helix screw thread elasticity heat exchange bundle, eliminate the stress
•Design flux speed is 5.5m/s, less dirt
•Big flow volume
•Compactable
•Easy installation and durable
