Specialty Expressions: heap
| Expressions | Domain | Definition | |
| Adaptive heap sort | Math | A variant of heapsort that uses a randomized binary search tree (RBST) to structure the input according to any preexisting order. The RBST is used to select candidates that are put into the heap so the heap doesn't need to keep track of all elements. (references) | |
| Binary heap | Math | A complete binary tree where every node has a key more extreme (greater or less) than or equal to the key of its parent. (references) | |
| Binomial heap | Math | A priority queue made of a forest of binomial trees with the heap property numbered k=0, 1, 2, ..., n, each containing either 0 or 2k nodes. Each tree is formed by linking two of its predecessors, by joining one at the root of the other. The operations of insert a value, decrease a value, delete a value, and merge or join (meld) two queues take O( log n) time. The find minimum operation is a constant (1). (references) | |
| Fibonacci heap | Math | A heap made of a forest of trees. The amortized cost of the operations create, insert a value, decrease a value, find minimum, and merge or join (meld) two heaps, is a constant (1). The delete operation takes O (log n). (references) | |
| Fiery heap | Mining | Eng. A deposit of rubbish and waste or unsalable coal that ignites spontaneously. (references) | |
| Hash heap | Math | An efficient implementation of a priority queue. The linear hash function monotonically maps keys to buckets, and each bucket is a heap. (references) | |

| Heap clouds | Geography | Clouds of appreciable vertical development. Source: European Union. (references) | |
| Heap decommissioning | Mining | Legal closure of a heap leaching operation. Depends on individual State regulations, but includes requirements for physical stability and chemical effluent requirements for metals and pH. A monitoring period is included.Syn:heap closure. (references) | |
| Heap leach | Energy | A method of extracting uranium from ore using a leaching solution. Small ore pieces are placed in a heap on an impervious material (plastic, clay, asphalt) with perforated pipes under the heap. Acidic solution is then sprayed over the ore, dissolving the uranium. The solution in the pipes is collected and transferred to an ion-exchange system for concentration of the uranium. (references) | |
| Heap leach pad | Environment | A large impermeable foundation or pad used as a base for ore during heap leaching. (references) | |
| Heap leach solutions | Energy | The separation, or dissolving-out from mined rock of the soluble uranium constituents by the natural action of percolating a prepared chemical solution through mounded (heaped) rock material. The mounded material usually contains low grade mineralized material and/or waste rock produced from open pit or underground mines. The solutions are collected after percolation is completed and processed to recover the valued components. (references) | |
| Heap leaching | Environment | A low-cost technique for extracting metals from ore by percolating leaching solutions through heaps of ore placed on impervious pads. This method is generally used on low-grade ores. (references) | |
| Heap leaching | Mining | A process used for the recovery of copper, uranium, and precious metals from weathered low-grade ore. The crushed material is laid on a slightly sloping, impervious pad and uniformly leached by the percolation of the leach liquor trickling through the beds by gravity to ponds. The metals are recovered by conventional methods from the solution. (references) | |
| Heap Leaching (Mining) | Administration | Heap leaching is a chemical process used to extract precious and other metals from vast amounts of earth and rock material. Tiny gold and silver particles dispersed throughout massive ore bodies can be economically recovered by leaching operations. However, due to the reactive nature of the chemicals used, environmental hazards may be created if care is not taken. Large quantities of naturally-occurring heavy metals and mineral salts are exposed and concentrated through this mining process. In the case of gold mining, a dilute cyanide solution is sprinkled over heaps of crushed rock, underlain by synthetic liners. The cyanide chemically bonds with the microscopic gold particles, which are then collected at the bottom of the heap in plastic liners for further processing. When the gold has been removed by this process, the heaps become a waste product requiring management and control well into the future. Heaps are typically full of residual dilute cyanide solution which, along with precipitation directly on the heap, will continue to drain through the heap. Because the heaps may contain residual cyanide, selenium, arsenic, mercury and various salts, the drainage solution may be hazardous to surface and groundwater supplies and the environment. Quite often, the least-costly manner in which to dispose of this continuous heap drainage is through a leach field and into the ground, where it may have adverse affects on the quality of groundwater, potentially contaminating water supplies for agriculture, human consumption and wildlife.

| Heap property | Math | Each node in a tree has a key which is more extreme (greater or less) than or equal to the key of its parent. (references) | |
| Heap rinsing | Mining | Method used to remove soluble constituents remaining within a heap leach pile after the metals concentration decreases to levels below economic limits. Simple water rinsing, chemical, or biological techniques or combinations thereof may be employed. (references) | |
| Heap roasting | Mining | Removal of sulfur from pyritic ore by burning in heaps, perhaps with aid of fuel. (references) | |
| Heap sampling | Mining | Method of reducing a large sample of ore to yield a representative sample. A conical heap is made by shoveling the material accurately on to the apex so that it runs down equally all around. The heap can then be flattened somewhat by rubbing with a spade, and is shoveled into four equal heaps, the same amount being taken from the base of the cone each time the worker goes around. Of the four smaller heaps thus formed, two are discarded and two retained. These may now be crushed to improve the ease of thorough mixing, and are then formed into another cone in the same way as the first. The process is repeated, with periodic size reduction of the retained portions, until the required small sample has been produced. (references) | |
| K-ary heap | Math | A complete tree where every node has a key more extreme (greater or less) than the key of its parent. Each node has k or fewer children. (references) | |

| Shadow heap | Math | A heap, implemented in an array, adjacent to an unordered table. The shadow is the table nodes and all their (recursive) parents, by array index, in the heap. (references) | |
| Spoil heap | Mining | A. The pile of dirt produced by mining operations and stacked at the surface of a mine either in conical heaps or in layered deposits. Syn:dump; tip b. A pile of refuse material from an excavation or mining operation; e.g., a pile of dirt removed from, and stacked at the surface of, a mine in a conical heap or in layered deposits, such as a tip heap from a coal mine.See also:spoil bank e.g., a pile of dirt removed from, and stacked at the surface of, a mine in a conical heap or in layered deposits, such as a tip heap from a coal mine.See also:spoil bank.
