IRON OXIDE REMOVAL FROM SOILS AND CLAYS BY A
2013-1-1 It was found that the bicarbonate-buffered Na 2 S 2 O 4-citrate system was the most effective in removal of free iron oxides from latosolic soils, and the least destructive of iron silicate clays as indicated by least loss in cation exchange capacity after the iron oxide removal treatment. With soils the decrease was very little but with the very susceptible Woody district nontronite, the decrease was

(iron, rust, copper, bronze) Iron or rust stains are orange to brown in color and follow the shape of the staining object such as nails, bolts, screws, cans, flower pots, metal furniture. Copper and bronze stains appear as green or muddy-brown and result from the action of moisture on nearby or embedded bronze, copper or brass items.

Ferrous Iron Removal Promotes Microbial Reduction of ...
2019-5-25 Semicontinuous cultures were used to assess the effect of aqueous Fe(II) removal on the dissimilatory reduction of crystalline Fe(III) oxides by Shewanella alga strain BrY. Aqueous phase replacement in semicontinuous cultures (average residence time of 9 or 18 days) resulted in a 2−3-fold increase in the cumulative amount of Fe(II) produced from synthetic goethite reduction over a 2-month ...

US4405588A - Process of removing iron impurities from ores ...
A process of removing iron impurities from ores, particularly useful for removing stains of iron impurities adhered to silica sand particles, comprises grinding the ore, washing and desliming the ground ore to remove the major part of the clay-type binder, attrition-scrubbing the deslimed particles to release further amounts of binder therefrom, washing and desliming to remove said binder ...

The Jurassic Navajo Sandstone exposed in southern Utah contains abundant, diverse, and well-documented examples of Fe oxide (e.g., hematite and goethite) concretions (e.g., Utah “marbles”) that have morphological similarities to the Mars “blueberries” in the deposits of Meridiani Planum (Chan et al., 2004, 2005).Although no single terrestrial analog is likely to be a perfect match for ...

Morphologic Clues to the Origins of Iron Oxide–Cemented ...
These iron oxide concretions typically display a rinded structure: dense sandstone rinds cemented by iron oxide surround pale, iron-poor sandstone cores. Within a single structure, the iron-rich rinds may be single or multiple. Pseudomorphs of siderite are present in local residual, iron-rich cores of boxworks.

CHARACTERIZATION AND REMOVAL OF FILTER CAKE
2018-8-1 Menzel (1973) introduced FER-O-BAR (synthetic iron oxide, manufactured from pyrite). It has been tested both in the lab and the field. Conclusions were drawn by comparing FER-O-BAR with barite: 1. Higher specific gravity (4.7 over 4.2), 2. Abrasivity is similar or lower, and lower than natural iron oxide

2001-1-30 Iron sulfide species have been known to cause operational problems in the oil industry. The presence of iron sulfide particles in the injected water can cause loss of injectivity in power water injectors 1–3 and water disposal wells. 4 Accumulation of iron sulfide and biomass around downhole screens and perforations can cause loss of productivity of water supply wells. 5 Build-up of iron ...
