Ag/Au Total Production Ratio and Au-Ag Minerals from Vein ...

64 major vein-type and disseminated-type deposits were estimated from various records (e.g. Geological Survey of Japan, 1980), as shown in Table 2. The Ag/Au ratio of the Type 1-A is lower than that of the Type 1-B from which base metals other than Au …

Geochemical behaviour, fate and impacts of Cu, Cd and Zn ...

The now abandoned mine at Britannia Beach is a source of acidity and heavy metals to Howe Sound. Using evidence from monthly field sample collections over an entire year, the dispersion patterns of Cu, Cd and Zn in the estuary were elucidated. Acid mine drainage discharged to Howe Sound via Britannia Creek was found to mix predominantly with the brackish surface waters, since a pronounced ...

Odin Mine - Wikipedia

Odin Mine is a disused lead mine in the Peak District National Park, situated at grid reference .It lies on a site of 25 hectares near the village of Castleton, England.It is the oldest documented mine in Derbyshire and is thought to be one of the oldest lead mines in England. The mine is a Scheduled Ancient Monument and has biological and geological significance within the Castleton Site of ...

Odin Mine nucleated lead mine and ore works, 350m WNW of ...

This part of Odin Mine is divided by the modern road from Castleton to Mam Tor. The ore works lie to the east of the road and include dressing floors and areas of dressing waste and a crushing circle used in the breaking down of lead ore. The crushing circle comprises a gravel-bedded circular iron track with a diameter of c.5.5m.

PorterGeo Database - Ore Deposit Description

The deposit was discovered in 1917, with production commencing in 1952 based on a reserve of 2.6 Mt @ 2.4% Pb, 4.2% Zn, 0.22% Cu, 17% S. Production between 1957 and 1997 totalled 5.0 Mt @ 4.0% Zn, 2.0% Pb, 0.15% Cu (Bjerkgård, 1999). The most recent source geological information used to prepare this summary was dated: 1989.

Phytostabilization of Pb-Zn Mine Tailings with Amorpha ...

A greenhouse pot trial was conducted to investigate the effect of organic amendments combined with triple superphosphate on the bioavailability of heavy metals (HMs), Amorpha fruticosa growth and metal uptake from Pb-Zn mine tailings. Cattle manure compost (CMC), spent mushroom compost (SMC) and agricultural field soil (AFS) were applied to tailings at 5%, 10%, 20% and 30% w/w ratio, whereas ...

Evaluating Remedial Alternatives for an Acid Mine Drainage ...

A post audit for a reactive transport model used to evaluate acid mine drainage treatment systems is presented herein. The post audit is based on a paired synoptic approach in which hydrogeochemical data are collected at low (existing conditions) and elevated (following treatment) pH. Data obtained under existing, low-pH conditions are used for calibration, and the resultant model is used to ...

to 10 460 mg.kg-1 for total Zn, 2 100 mg.kg-1 for total Pb and 62.08 mg.kg-1 for total Cd. The tailings have presented a fine unconsolidated texture that accelerated the dispersion of the particles rich in heavy metals. Geochemical analysis of soil has revealed high total contents of Pb, Zn and Cd, respectively: 3 646, 3 236 and 17 mg.kg-1 ...
