Hematite is excellent weighting agent with slower solid content

Hematite is a high-quality material and weighting agent exist underground. In drilling mud, it has a crystal structure and it is so beneficial being this kind of structure. It increases the mud weight additionally It is so heavy when you compare this with same sizes item.

When hematite uses in drilling fluid or fluid helps in achieving a higher weight for the drilling fluid. On an ideal consideration, a low mud weight or as low as the weight of water is a beneficial choice to achieve the most favorable rates of penetration in the formation. But in industrial practice and real-life scenarios, a mud weight of much higher values is needed to perform the primary job of suppressing the subsurface pressure. The control of drilling fluid weight is critical, because an unnecessarily heavy drilling mud can cause breakdown of formations leading to loss of circulation or even a complete loss of a well, and reduction in drilling rate. On the other hand, if the mud weight becomes too small to suppress subsurface pressures, well kick and or blow out may occur.

Hematite effect using in drilling

Benefits of hematite usages

• To control and achieve certain rheological properties of the drilling fluid, the concentration of mud additives is very much a central element. Due to changes in the concentration hematite, significant changes were observed in the weight, plastic viscosity, yield point

• Gave notably higher mud weight, plastic viscosity, yield point and gel strength, when same concentrations were being added to the drilling fluid.

• Giving a higher weight than other product like barite is a result of higher specific gravity

• Contributing better values to the other rheological properties, is attributed to the presence of iron oxides in the material, which also have lower rates od sedimentation, as compared to barite.

Composition of hematite

Pure hematite has a composition of about 70% iron and 30% oxygen by weight. Like most natural materials, it is rarely found with that pure composition. This is particularly true of the sedimentary deposits where it is forms by inorganic or biological precipitation in a body of water

Other usages of hematite

It is the most important iron in the world and it contains high rate magnetite for easy process. The mines is the largest mine also especially in Iran. Fine powder of hematite can use in cosmetic and paint. It is a minor gem material used to produce cabochons, beads, small sculptures, tumbled stones, and other items. It also has very positive effect on human body. It is cheap material even use as a protective for X-ray and also uses in medical. When it mixes with water you can get very high composition for using in “float-sink” processing of coal and other mineral material. The crushed coal, which has a very low specific gravity, is placed on the heavy liquid and the light clean coal floats, while high-specific-gravity impurities such as pyrite sink

It also uses for polishing material for jewelry and the other areas. It can be added to crushed corn cob media or crushed walnut shell media for tumble-polishing brass shell casings. Jeweler’s rouge is a paste used on a soft cloth to polish gold and silver jewelry.
