A system and method for handling slag in a slag pit includes an equilibrium or balance crane equipped with a quick connect coupling. A drop-ball fixture and drop-ball reduces the size of the slag, as needed, then the boom assembly of the crane releases the drop-ball fixture and engages an excavating tool, such as a clamshell bucket, a bucket, or a grapple. An elevated control station provides an operator with improved line-of-sight visibility.
C22B 7/00 - Working-up raw materials other than ores, e.g. scrap, to produce non-ferrous metals or compounds thereof
B66C 1/06 - Load-engaging elements or devices attached to lifting, lowering, or hauling gear of cranes, or adapted for connection therewith for transmitting forces to articles or groups of articles by magnetic means electromagnetic

B66C 23/53 - Floating cranes including counterweight or means to compensate for list, trim, or skew of the vessel or platform
B66C 23/58 - Cranes comprising essentially a beam, boom or triangular structure acting as a cantilever and mounted for translatory or swinging movements in vertical or horizontal planes or a combination of such movements, e.g. jib cranes, derricks or tower cranes arranged to carry-out a desired sequence of operations automatically, e.g. hoisting followed by luffing and slewing
Residuals, such as slag particles, from iron- and/or steel-making, and/or water-leached eluates thereof, are added directly to a conventional or multi-staged anaerobic digester or other sewage sludge or biosolid handling process. The slag particles or other residuals sorb, sequester, immobilize, or otherwise promote the removal of phosphorus and/or sulfur from wastewater, sludge, or biosolids being treated, such that the associated aqueous phase concentrations of phosphorus and sulfur are significantly reduced.
C02F 103/16 - Nature of the water, waste water, sewage or sludge to be treated from metallurgical processes, i.e. from the production, refining or treatment of metals, e.g. galvanic wastes
Disclosed herein is a geocomposite device in the form of a web-based mat or board, wherein the device includes one or more reactive particulates. The geocomposite mat includes at least first and second geosynthetic layers and a reactive flow layer disposed between the first and second geosynthetic layers, the reactive flow layer comprising a nonwoven core and a reactive particulate, wherein the mat facilitates a flow of fluid therethrough, further wherein the flow of fluid causes contact of at least a portion of the fluid with the reactive particulate while substantially retaining the reactive particulate within the mat.
Disclosed herein is an elution device comprising one or more inlets and one or more outlets and defining an interior volume comprising steel slag, wherein the elution device is mounted to a support and situated substantially above ground level. One or more inlets and one or more outlets are disposed to facilitate fluid flow from an inlet toward an outlet to cause contact of the eluant with the slag for a period sufficient to form an eluate. Also disclosed herein are methods of applying an eluant to the elution device and dispensing an eluate from an outlet proximal to a distressed water source to form a treated water source. Also disclosed herein are methods of applying an eluant to the elution device and dispensing an eluate from an outlet proximal to one or more areas having living plants thereon or therein.
