The present invention relates to the large-scale production of polymer nanocomposite with a matrix of ultra-high-molecular-weight polyethylene (UHMWPE) additivated with carbon nanomaterial (or nanofiller), and its use in ore transfer points. Suitable routes for processing polymer materials with ultra-high viscosity and additivated with 2D carbon nanomaterials in small fractions have been developed as part of the present invention to substantially improve mechanical, tribological and surface performance. Mixing in the molten state is the most industrially efficient and viable method for obtaining polymer nanocomposite materials. However, it is very difficult to achieve ideal dispersion and homogenization of this type of 2D nanomaterial with these matrices. In addition, polymers with high molar mass entail many inherent processing difficulties. The invention stresses that the pre-exfoliation of the nanofillers is essential to achieving significant dispersion of the nanofillers, enhancing the effects on the properties. The results presented demonstrate that the process developed produces nanostructured materials with suitable morphologies, and consequently excellent mechanical and surface properties.

An apparatus and method for sensing a leakage current along a primary conductor are provided. A first fault detection module is deployed at a first location along the primary conductor and a second driver module is deployed at a second location along the conductor, where the conductor passes through current sensors at each of the modules. The modules are further linked by a safety cable, which also passes through the current sensors. The driver module drives a compensation current in the safety cable to drive the net current passing through the driver current sensor to zero. The fault sensing module senses the net current passing through its current sensor. When the sensed current deviates significantly from zero, the fault sensing module generates a leakage current indication signifying a potential ground fault between the two modules.

The proposed invention is a process for obtaining the ore dust suppressant resin with the chemical recycling of Poly thermoplastic polymer (Ethylene Terephthalate) or PET. It is proposed a method for obtaining the resin by using the depolymerization reaction methodology of the Poly polymer (Ethylene Terephthalate) obtained from post-consumption PET bottles, in the presence of cationic surfactant hexadeciltrimetrilamonio bromide (CTAB). The resin is thus obtained being subsequently added to the same PVP K-90 (Polyvinylpyrrolidone) as increasing load on the final viscosity of the resin. Other additives such as lignin extracted from plants such as leaves and tree branches may also be added, in this case, incorporated to make the resin more hydrophobic.

The present invention refers to a system and method for the totally dry treatment of iron-ore wastes from previous mining operations, suitable for both the processing of ore wastes deposited in barrages and wastes stored in piles. The present invention solves the problems of magnetic separation processes that employ the wet and waste-dewatering way, eliminating the risks which throwing solid wastes into retention barrages bring by a system and method wherein the moisture degree of the ore is reduced by means of a mechanical stir dryer (using natural gas to prevent contamination), which is then sorted into various factions and finally separated magnetically, with the important difference of being an entirely dry process.

The present invention proposes an efficient, advantageous and complex process route for producing sodium borate and lithium carbonate from brine that is exceptionally rich in Ca and Mg, as well as lithium and boron. The aim is to outperform the technical and economical scenarios provided by the currently known technologies and process routes. According to the present invention, the process used for producing lithium carbonate comprises the following steps: (i) filtering brine that is rich in Ca and Mg; (ii) treating the filtrate with hydrochloric acid; (iii) extraction using a solvent (SX); (iv) first purification of the filtrate; (v) second purification of the filtrate; (vi) third purification of the filtrate; (vii) reacting the filtrate with supersaturated sodium carbonate; (viii) thickening and filtering the resulting pulp produced at the end of step (vii); and (ix) washing and drying the lithium carbonate. Furthermore, according to the present invention, the process used for producing sodium borate comprises the following steps: (i) filtering brine that is rich in Ca and Mg; (ii) treating the filtrate with hydrochloric acid; (iii) producing Na2B4O7 by extraction of the acidified brine produced at the end of step (ii) using a solvent (SX); (iv) reducing the quantity of water in the solution produced at the end of step (iii) by solar energy, to obtain a saturated condition; (v) crystallizing the Na2B4O7 produced in step (iii), using an evaporator and vapour to heat the solution and cause evaporation of water in the form of water vapour, as well as to crystallize Na2B4O7; (vi) crystallizing Na2B4O7 by cooling; (vii) recycling the mother liquor to feed the evaporator used in step (v).

The present invention provides a suspension and vibration isolation system having cable isolators. The cable isolators employ low-friction air-bearing pneumatic cylinders and cables to isolate a suspended payload from vibrations of a carrier or to isolate the carrier from vibrations of the payload. Using such air-lubricated cylinder to piston interfaces virtually eliminates static friction and so improves the effectiveness of the isolation for small forces and displacement. The use of pneumatic cylinders also permits the system to be tuned to the required resonance frequency to isolate the payload from vibrations in a desired frequency band.
