The rare earth elements are indispensable elements.Although many rare earth elements exist in comparatively abundant resource amounts, concentrated minerals are unevenly distributed on the earth, and are not produced in Japan. The rare earths are heavy metals, and are harmful if the rare earths are emitted into the environment. For this reason, the rare earth elements are desirably reused from products or wastes.Although high-concentration rare earth ions can be precipitated and removed by pH control or the like, low-concentration rare earth ions can be removed with the use of an ion-exchange resin or a chelating resin.However, in these techniques, all the rare earths and heavy metals are precipitated, or adsorbed by a resin, which makes it difficult to reuse the rare earths.It is known that a compound having a phosphate group can selectively adsorb rare earth ions. For example, it has been known that aluminum can be separated from cerium with the use ...

Method for displacing large blocks of earth

A method for elevating extremely large blocks of earth by displacement with a slurry composed of water and locally excavated materials. The blocks are separated on lateral faces by variously drilling, jetting, fracturing, and kerf cutting operations. The blocks are separated at the lower end by notching and hydraulic fracturing. Block movement is started by injecting gelled fluid into the narrow separations. In one set of applications the high density slurry filling the side clearances is less dense than the block being elevated. In these cases the earth blocks are displaced upward by injecting fluid into the underside, and the non hydrostatic component of the displacement pressure is contained by the gel strength of the slurry filling the narrow side clearance. In a second set of applications the blocks being elevated contain a high percentage of coal, and slurry filling the side clearances exceeds the block density. The blocks are then displaced upward by hydrostatic pressure. The method has a wide range of applications which include elevating a block and cementing it in place to form a storage cavity, elevating a block and fragmenting a hydrocarbon containing section into the resulting cavity in preparation for in situ recovery of hydrocarbons, and elevating a block to recover the coal contained in the block.

Method for supplying local waters for watering the developed peatlands and device for its implementation

FIELD: peat. SUBSTANCE: group of inventions relates to production of peat, namely to work on remediation of peat bogs, and, in particular, to watering of worked-out peatlands. Method of supplying local waters for watering the developed peatlands consists in creating the use of water from an accessible source, moving it to the flooded areas of the worked peat bog and creating conditions for the source, which runs along the slope of the terrain. Water source is the area of the stream channel. Moreover, the source is further divided in the middle part of a bulk embankment into independent channels, the initial sections of which are connected with the upper tail, and the end sections – with the main sites of the peat deposit development. In this case, the end portion of each channel is made in the plan, tapering from the upper tail to the tailrace with a knee-shaped turn of not less than 180° in relation to the initial section. Intercept the flooded section of the canal in the form of a floodplain. At the same time, in each channel, a partitioning water-transfer structure is placed in the form of a box from the side of the tailrace. At the same time, a partitioning water-repellent structure in the form of a box with the possibility of taking water out of the floodplain is carried out with automatic discharge of water at the level of the upper tail and flooding the area of the worked peatland to its estimated filling.
