Lead-Zinc Mining--Evaluation of Plantings
Photograph of the area around the Eagle-Pichers Mine, Picher, Oklahoma. Slimes Pond Evaluation of plantings in Commerce, Oklahoma. This is a view of the IMCO mulch tiller manufactured by the Independent Manufacturing Company, Neodasha, Kansas, as used on the Eagle-Picher Slimes Pond hay mulching operation. Note the iron which weighs some 60 to 70 pounds each. These served to put pressure on the treader adequate to press hay into sand. Three tons of hay mulch per year were applied and anchored following the planting of a native grass seed mixture prepared by the Soil Conservation Service Plant Materials Center, Manhattan, Kansas. OK-3013-6.

Selective Recovery of Enriched Uranium from Inorganic Wastes
Uranium as U(IV) and U(VI) can be selectively recovered from liquids and sludge containing metal precipitates, inorganic salts, sand and silt fines, debris, other contaminants, and slimes, which are very difficult to de-water. Chemical processes such as fuel manufacturing and uranium mining generate enriched and natural uranium-bearing wastes. This patented Framatome ANP (FANP) uranium recovery process reduces uranium losses, significantly offsets waste disposal costs, produces a solid waste that meets mixed-waste disposal requirements, and does not generate metal-contaminated liquids. At the head end of the process is a floating dredge that retrieves liquids, sludge, and slimes in the form of a slurry directly from the floor of a lined surface impoundment (lagoon). The slurry is transferred to and mixed in a feed tank with a turbine mixer and re-circulated to further break down the particles and enhance dissolution of uranium. This process uses direct steam injection and sodium hypochlorite addition to oxidize and dissolves any U(IV). Cellulose is added as a non-reactive filter aid to help filter slimes by giving body to the slurry. The slurry is pumped into a large recessed-chamber filter press then de-watered by a pressure cycle-controlled double-diaphragm pump. U(VI) captured in the filtrate from this process …

Pollution of ground water due to inactive uranium mill tailings. Summary of progress, October 1, 1979-September 30, 1981
An extensive program of characterization of several inactive uranium tailings piles has been carried out in the past year. The geotechnical engineering program conducted a drilling program at the Salt Lake City and Grand Junction sites. The locations of slimes and sands in these sites hve been characterized. In general, it was found that slimes exist in the impoundments in lower percentages than normally produced from mill tailings. Permeability tests were conducted yielding values ranging from 10/sup -3/ cm/sec to 10/sup -6/cm/sec. The geochemical studies made considerable progress in the past year. Extensive sampling of several sites was conducted. Sampling programs have been completed for seven sites and are underway for nine other sites. The work to date has indicated the importance of salts in controlling the direction and rate of movement of contaminants. The work has also indicated that a number of non-radioactive elements such as As are of environmental importance. The work also indicates the importance of the fact that the tailings piles are out of chemical equilibrium with their environment. Computer software was developed and implemented for data storage and retrieval. Automation hardware was installed and tested for the Inductively Coupled Plasma Emission Spectrometer. A number of …
