Bob Hedin, Hedin Environmental, "Effective Passive Treatment of Coal Mine Dra...Michael Hewitt, GISP
Contaminated mine drainage on abandoned coal mine sites can be treated by passive or active treatment techniques. Passive treatment is less costly than active treatment, but its reliability is often questioned. This paper presents a simple design approach that has been used to design passive treatment systems in Pennsylvania for the past 20 years. Four systems that demonstrate commonly utilized passive technologies are described and long-term data are presented. The systems have provided highly reliable and effective treatment for 3-18 years. The data demonstrate that properly designed, constructed, and maintained passive treatment systems are a highly cost-effective solution for contaminated mine discharges on AML sites.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

19. Artisanal /SSM Gold Ore Pool Leaching Flowsheet
An Innovative Pool Leaching System can improve gold recovery rate up to 90%
20. Pool Leaching Process Description
Ores/Tailing materials are transported to process site;
Materials are crushed (if necessary) using hammer crusher;
Crushed materials are loaded into leaching pool with loader;
Material is leached in pool for about 10 days; leaching
solution is cycled three times in the whole process before
discharge the material out of the pool;
Pregnant solution is pumped into CIC; diluted solution is
pumped back to dilute solution pool for recycling.
Gold bearing carbon will be burned and gold will be recovered
through refinery;
Leached ores in pool are discharged by excavator and reload
new ores into the pool for next leaching process.
21. Pool Leaching Advantages
• Simple system: loader, excavator, generator, water pump, Eco-
goldex reagent, activated carbon,
• Low capital investment requirement. A SSM operation needs
only about 100K-150K USD to start,
• Portable and scalable, n x1000 tonnes – 100K tonnes
materials are workable with pool leaching method,
• Safe, green and environmentally clean, easy to operate,
• Leaching solutions are in a closed system and recycled,
processed materials no de-toxic process because they contain
no contamination chemicals (actually can be used as
fertilizer).
23. The most commonly used VAT leaching facilities in developing / undeveloped
countries have their innate technical drawback which causes Poor Permeability
and circulation of leaching solution and low gold leaching rate and recovery rate.
