摘要： THIS invention relates to a method of disposing of residues from the comminution and processing of ores. The method includes the steps of classifying the processing residues into a water permeable sand fraction and a tailings fraction and depositing the tailings fraction and the sand fraction to form a multilayer structure contained by at least one containment wall (14) with the sand fraction forming continuous channels (12) through the tailings fraction (10) to allow water contained in the tailings and sand to flow by gravity, through the sand channels, to water discharge points (16), and recovering the water (18) from the water discharge points.

摘要： Described herein are technologies for concentrating rare-earth elements from a heavy fraction of grit in gangue produced in kaolin mining. In some examples, grit is separated as a non-clay fraction of gangue produced in a kaolin mining operation. The grit is separated into a heavy mineral grit sub-fraction and a light mineral grit sub-fraction. Rare-earth elements, particularly heavy rare-earth elements, are thereafter extracted from the heavy mineral grit sub-fraction using various extraction technologies.

摘要： Methods and apparatus for separating and removing aflatoxin-contaminated corn from batches of corn by a floating process, thus producing a distinguishable floating mat of contaminated corn and a separate submerged bed of uncontaminated and less contaminated corn. The methods of this disclosure include removing the floating contaminated corn mat by a vacuum mechanism or by liquid flow. The methods reduce the aflatoxin level in the submerged corn bed as much as 80% from the initial aflatoxin level, while removing no more than 15% from the batch of corn.

摘要： A process for extracting and purifying naturally occurring zeolite from ores in the presence of other mineral phases by using mechanical dispersion and differential suspension to remove a majority of the clay content of the ore. The process continues by removal of contaminants with a higher mass to surface area ratio than that of the desired zeolite product by employing the properties of demineralized water in combination with a countercurrent flow separation column. No chemical flocculating or flotation agents need be employed in the process.

摘要： A method and apparatus for sorting particles moving through a closed channel system of capillary size comprises a bubble valve for selectively generating a pressure pulse to separate a particle having a predetermined characteristic from a stream of particles. The particle sorting system may further include a buffer for absorbing the pressure pulse. The particle sorting system may include a plurality of closely coupled sorting modules which are combined to further increase the sorting rate. The particle sorting system may comprise a multi-stage sorting device for serially sorting streams of particles, in order to decrease the error rate.

摘要： The invention relates to a method for the recycling of plastic-coated cable residues, which comprise a metal core and a plastic jacket, wherein the metal parts are separated from the jacket and are separately recovered. The cable residues are communited and the chopped material is softened in a swelling container (10) with a swelling agent for the plastic. Subsequent to softening, the mass flow is fed with the swelling agent to a roller cone mill (13). The roller cone mill (13) flexes the chopped material and destroys the macrostructure of the cable pieces mechanically. The metal particles are separated from the jackets by way of stirring in a stirrer (14), and the multi-phase mixture is transported to a metal sedimentor (16). The heavier metal particles sink down in the metal sedimentor (16) based on gravity and separate themselves from the lighter plastic particles. The transport speed of the transport flow in the metal sedimentor (16) is selected such that the metal particles corresponding to their size-dependent different sinking speeds sink up to the outlet out of the metal sedimentor (16). A countercurrent of swelling agent is entered into the transport flow, where the countercurrent discharges the lighter plastic particles from the transport flow. Thereupon, the countercurrent with the plastic particles is led out of the metal sedimentor (12) as a partial flow and is led into a plastic sedimentor (38) for the sedimented depositing of the plastic particles. The method is performed sealed against gas and the swelling agent is cyclically recovered.

摘要： A gravitational separation device is provided and the process is provided involving a packed column containing a packing material and having a device for vibrating the packed column and the particles. The gravitational separation device allows for efficient and effective separation of solid particles having different densities. The process preferably involves conditioning an aqueous pulp of mineral ore with a dispersant and feeding the dispersed aqueous pulp into an inlet into an intermediate section of the packed column and forming a high density bed of high density particles in a lower portion of the column, and forming a low density bed of low density particles in an upper portion of the column. Tailings are removed from the upper end of the column and concentrated mineral ore having reduced levels of gangue are removed from the bottom of the column. The device and process are especially useful in the separation of silica particles having small particle sizes from iron ore particles having small particle sizes.
