What is Process Mining? | IBM

 · Process mining sits at the intersection of business process management (BPM) and data mining. While process mining and data mining both work with data, the scope of each dataset differs. Process mining specifically uses event log data to generate process models which can be used to discover, compare, or enhance a given process.

Effects of iron-ore mining and processing on metal ...

 · Mining and associated smelting and metal processing activities have led to perturbations in the cycling of metals in the surface environment. In this context, iron-ore mines act as important sources of major metals, mainly Fe and Mn, but also associated trace metals into the environment (Ratha and Venkataraman 1995; Wong 1981; Zabowski et al. 2001).

Beaches and Coastal Landforms

Coastal processes create many erosional or depositional features we see when visiting the National Parks such as: Beach Ridges Beach ridges are wave deposited sand ridges running parallel to shoreline. Wave-Cut Scarps A wave-cut scarp is a steep bank created by wave erosion.

Metal Dispersion Resulting from Mining Activities in ...

Acid rock drainage (ARD) and disposal of tailings that result from mining activities impact coastal areas in many countries. The dispersion of metals from mine sites that are both proximal and distal to the shoreline can be examined using a pathways approach in which physical and chemical processes guide metal transport in the continuum from sources (sulfide minerals) to bioreceptors (marine ...

Sea Erosion

 · Next, the coastal zone is undergoing severe erosion caused by natural coastal processes including climate changes. We know that climate changes are a big problem and the effect will be just increasing in a few decades later. Indeed, by the presence of climate changes, it has been worsening the level of erosion in some coastal countries.

Mining of Coastal Materials | SpringerLink

Considering only coastal areas, those adjacent to the shoreline and extending seaward through the breaker (surf) zone (U.S. Army Coastal Engineering Research Center, 1966) and landward through the highest surfaces subject to modern processes of wave alteration, the area represented (based on estimates by Kuenen, 1950) is a little less than 1% ...

Coastal Erosion

Ye Yincan et al, in Marine Geo-Hazards in China, 2017. 2.1 Basic Concept of Coastal Erosion. Coastal erosion is a result of human activities and natural environment changes making the coastal dynamic action (wave, current, wind) lose balance in the coastal process, and the long-term loss of sediments of coastal zone results in the destruction process of coastline retreat and beach erosion.

Morocco Mining

Types of coastal sand mining in Morocco We observed several types of coastal sand mining south of Tangiers in Morocco in July, 2007. The following examples are listed in order of the degree of economic and environment al damage. The first approach, bluff top mining is the least damaging and

A 10 km thick homoclinal sequence of intermediate volcanic and sedimentary Jurassic rocks crops out in the Michilla mining area, Coastal Range, northern Chile (22-22°45S, 70-70°15W). Cretaceous plutons, intermediate to acid in composition, intrude this sequence together with numerous small basic to acid dykes and stocks. Main deposits are stratabound Cu-(Ag) with the ore minerals emplaced at ...

What is dredging?

Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural process of sand and silt washing downstream—gradually fills channels and harbors.
