摘要： A method for removing impurities from a waste solid to provide at least a portion of a suitable crystallizer feed to a process for making crystalline sodium carbonate, bicarbonate, and/or other derivatives. The method comprises: contacting the waste solid with a leach solution to dissolve at least one impurity and dissolving the resulting leached residue. Leaching may include heap percolation. The leach solution may comprise a crystallizer purge liquor, a process waste effluent, a mine water, or mixtures thereof. The method may further comprise adding a magnesium compound to the resulting leached residue during or after its dissolution to remove another impurity. The waste solid preferably comprises a pond solid containing such impurities. The pond solid may be recovered from a pond receiving crystallizer purge liquor(s) and/or other process waste effluent(s). The pond solid may contain sodium carbonate, any hydrate thereof, sodium bicarbonate, and/or sodium sesquicarbonate. The impurities to be removed may comprise sodium chloride, sodium sulfate, silicates, and/or organics.

摘要： Utilization of mine methane produced by mining a non-combustible ore, such as trona, as an energy source for heat, steam, and/or power generation. Such utilization is beneficial for a surface appliance which is close to surface outlet(s) of mine methane recovery system(s). A method for reducing greenhouse gas emissions generated during mining of a non-combustible ore uses the combustion of co-produced mine methane. The mine methane is recovered in a mine ventilation air exhaust with very low methane content, and may be additionally recovered in a drainage gas, such as gob gas, with much higher methane content. The surface appliance may be selected from the group consisting of calciner, dryer, boiler, kiln, furnace, engine, turbine, power generation unit, co-generation unit, and any combinations thereof. Benefits may include reduction in energy purchases, reduction in greenhouse emissions, and/or gain through sale of carbon credits to the carbon market by registering carbon reductions.

摘要： Mining method for co-extraction of non-combustible ore and mine methane A method for co-extracting non-combustible ore (e.g., trona) and methane from an underground formation comprising at least one methane-bearing layer and a non-combustible ore bed having a rock roof, comprising: providing a well having a downhole end positioned above the ore bed roof; mining an ore region from an initial cavity and removing the mined ore, thereby creating a subsequent cavity; advancing the mining step to another ore region from the subsequent cavity; allowing the roof of the initial cavity to cave so as to create a gob; repeating the mining, advancing and caving steps, the caving being effective in generating fluid communication between the gob and the well downhole end and in fracturing the methane-bearing layer so as to release methane into the gob; and recovering a gob gas comprising released methane through the well to the surface.

摘要： In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘undercut’, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.

摘要翻译：特别是含有天然碱的矿床的原位溶液开采方法，其包括将在矿石钻出的钻孔内的矿石区域暴露于溶剂，并将期望的溶质溶解在暴露的区域内以提供液体并产生空隙的“ 底切“，这种底切使得矿石易于引力加载和破碎。未发现的矿石通过重力落入底切而不破坏矿顶，导致新鲜矿石暴露于溶剂中并防止溶剂暴露于屋顶附近的污染物质。期望的溶质最终从其地板直到其顶部溶解在整个床中。溶剂注射可以通过位于钻孔内部的导管输送，并且可以通过缩回或穿孔导管来移动。该方法可以采用推进的底切启动的向上倾斜和行进下倾，或者采用后退的底切开始向下倾斜和向上移动。
