Analytical models are of vital importance to study the dynamics complex systems, including heap leaching process. In this work, a methodology copper recovery in by means fit analytical that capture product variations agents as function feeding is proposed, establishing first mode operation keeping agent fixed (H2SO4) and second mode, where Cl− added accelerate reaction kinetics sulfide minerals...

A number of papers have used predicate languages over sets of abstract locations to model the heap (decorating a heap graph with the predicates, or in conjunction with an access path abstraction). In this work we introduce a new predicate, dominance, which is a generalization of aliasing and is used to model how objects are shared in the heap (e.g. do two lists contain the same set of objects?)...

This paper presents an axiomatic framework in Coq for verifying invariants on heap data structures such as lists and trees in a C-like language with a low-level store model. The goal of the framework is to detect common errors such as memory leaks, dangling pointers and looped data structures. The framework provides a language for expressing invariants, and a set of inference axioms for verifyi...

We present Alias Refinement Types (Art), a new approach to the verification of correctness properties of linked data structures. While there are many techniques for checking that a heap-manipulating program adheres to its specification, they often require that the programmer annotate the behavior of each procedure, for example, in the form of loop invariants and preand post-conditions. Predicat...

The percolation technique was used to examine the leachability of uranium from El-Sela mineralization. agglomeration effect, particle size, flow rates, free acidity, solid/liquid ratio, and ratio cobblestone effect were all studied in kinetics leaching. At a height 3.0 m within column, optimal ore found be 1:4, irrigation rate reduced 0.15 0.1L/m2/min, increasing 47.5 79%. Finally, column leach...
