    Abstract: Device for obtaining dust from minerals. The device has an excitation part for mechanical ultrasonic vibrations combined with a chisel. A suction device is provided to collect the dust produced. The device serves in particular to produce dust samples rapidly for quick analysis of minerals in prospecting, in the reconnaissance and evaluation of deposits and in the mining of minerals for the purposes of quality control, monitoring and controlling the mining process.

    Abstract: Process for sorting coarse to fine materials according to their chemical composition, in which samples are taken and analyzed, and in which the transporting and/or further processing of the materials is controlled according to the results of the analysis. The samples are taken in the form of an air swirled mixture of coarse dust and fine dust (i.e., particles with grain sizes of less than 200 .mu.m) which is obtained as a by-product or is produced artificially. The coarser dust is separated from the mixture. All of the fine dust or a fraction thereof is analyzed.

    Abstract: An apparatus for preparing samples taken from a flow of bulk material for the purposes of determining representative chemical and/or physical characteristics of the sampled material. The sampled material is removed in the form of a mix of fine and coarser particles of dust from the flow of bulk material by way of a suction conduit. The sample-preparing apparatus is positioned at a spacing from the intake opening of the suction conduit and at a spacing from the flow of bulk material, and comprises a first housing accommodating a first hollow strainer and a second housing downstream of the first housing and accommodating a second hollow strainer. Outside the second strainer, the second housing is communicated with a reduced pressure source for producing the suction effect to transport the dust particles of the sampled material through the two housings and, insofar as the grain size of the dust particles permits, also through the two strainers. The first strainer defines the upper separation cut-off limit of the relevant grain fraction required for analysis, and the second strainer defines the lower separation cut-off limit of the relevant grain fraction.
