chapter 2 - ore handling. ore handling is a key function in mining and mineral processing, which may account for 30–60% of the total delivered price of raw materials. it covers the processes of transportation, storage, feeding, and washing of the ore en route to, or during, the various stages of treatment in the mill.,'semantic process mining tools: core building blocks' by,recommended citation. de medeiros, alves; van der aalst, wil m.p.; karla, ana; and pedrinaci, carlos, 'semantic process mining tools: core building blocks' (2008).
in this paper, a multiperiod mip model is presented that optimizes (1) production schedules for multiple mines, (2) locations of new processing facilities, (3) type of processing facility for each processing site, (4) processed ore blending schedule for each process- ing facility, and (5) market selection. the model optimizes these by maximizing the total profit before,energy efficiency & copper hydrometallurgy,processes from ore in the ground to final salable cathode product (i.e. mining through electrorefining or electrowinning) to; - compare process routes, - identify and prioritize opportunities for energy reduction, and - support the global mining initiative, icmm and sustainable development initiatives
consensus sequences of event logs are often used in process mining to quickly grasp the core sequence of events to be performed in a process, or to represent the backbone of the process for doing other analyses. however, it is still not clear how many traces are enough to properly represent the underlying process. in this paper, we propose a novel sampling strategy to determine the number of,[pdf] process mining for clinical workflows: challenges,process mining is an emerging technology in the context of business process management with the goal to derive process models from observed system behavior. the global goals are: to detect previously unknown process structures, to implement consistent process controlling which may involve computation of realistic cycle times and frequency of occurrence of process pathways, or to quantify
process of expanding and modernizing their operations. when an area of suitable and mine-able rock is swallowed up by urban growth or when mining becomes prohib-ited by legislation or zoning, the result is called “resource sterilization.” limestone is a material of,the possible hydrologic effects of the proposed lignite,the present study investigates the possible hydrologic effects of the proposed lignite open‐cast mining in drama lignite field (north greece). recent years have seen a rapid increase in surface mining. this activity has generated a growing concern for the potential environmental impacts associated with large scale surface mining.
the international journal of mineral processing covers aspects of the processing of mineral resources such as: metallic and non-metallic ores, coals, and secondary resources. topics dealt with include: geometallurgy, comminution, sizing, classification (in air and water), gravity concentration, flotation, electric and magnetic separation,reclamation of degraded landscapes due to opencast mining,therefore, it is not only crucial to have a detailed understanding of the pre-mining environment, but also important to apprehend the utilized mining method in order to plan a meaningful surface rehabilitation, wherever possible (chamber of mines of south africa 2008). the process of removing, storing and subsequently replacing the soil during
24 june 2008. the gold value chain part ii - refining refiners exist because the gold that comes out of the mining process varies in purity and size but trading is more efficient if the units of trading (i.e. gold bars) are standardised. their basic job is to convert dore (the stuff from mines) into a,trace clustering in process mining,process mining has proven to be a valuable tool for analyzing operational process executions based on event logs. existing techniques perform well on structured processes, but still have problems discovering and visualizing less structured ones. unfortunately, process mining is most interesting in domains requiring flexibility.
– this paper seeks to examine the area of business process mining, providing an overview of state‐of‐the‐art techniques. an outline of the main problems experienced in the practice of process mining is given along with reference to work that addresses the most challenging issues experienced in this field. this paper also aims to examine the application of soft computing techniques to,process mining algorithm to discover non-certain choice,non-certain choice and parallel is a ubiquitous relation between tasks in the business process.modeling this kind of relation by traditional wf_net based method will cause duplicated tasks in the model,which brings difficulties to the process mining.based on event logs,in this paper the non-certain choice and parallel relation was defined,and meanwhile co-operating with synchronized-manager a
this paper gives out a brief survey on issues, challenges, approaches and related tools in behavior pattern mining area, and compares behavior pattern mining with workflow mining technology, which is the other sub field of process mining. to reply the problems proposed by behavior pattern mining, the process mining area gets its new motivation.,mine and process service, inc.,the pma-2008 pocket mining anemometer is the second generation of our battery-powered electronic anemometer for use in underground mining. still small enough to fit into a shirt pocket, the pma-2008 anemometer makes taking ventilation readings even easier than before!
the concept of process mining provides an interesting opportunity for providing a solution to this problem. process mining  aims at extracting process knowledge from a. fred, j. filipe, and h. gamboa (eds.): biostec 2008, ccis 25, pp. 425–438, 2008. c springer-verlag berlin heidelberg 2008,process mining for clinical workflows: challenges and,process mining for clinical workflows: challenges and current limitations martin lang ab1,thomas bÜrkle a,susanne laumannb,hans-ulrich prokoscha achair of medical informatics, university erlangen-nuremberg, germany bdpt. of image and knowledge management, siemens ag medical solutions, germany abstract. process mining is an emerging technology in the context of business
