Book Description
Excerpt from Mining and Milling of Lead and Zinc Ores in the Missouri-Kansas-Oklahoma Zinc District Several mill tests were made to determine in a general way the efficiency of the milling practice in this district and to discover at what stage of the process the losses were greatest. Making these mill tests proved difficult, for, because of the arrangement of the mills and the necessity of estimating the tonnage treated, systematic mill testing and sampling can be done at only a few plants. Many tables giving results of mill tests and screen tests have been omitted because they would serve only to emphasize the important points shown by other data given. The writer has tried to bring out the possibilities of making certain improvements that would effect a greater saving, and has endeavored to avoid the use of technical terms and phrases in order that all statements may be clear and easily understood.

Book Description
Excerpt from The Lead and Zinc Mining Industry: Of Southwest Missouri and Southeast Kansas The discovery of the zinc ore deposits of this, district was made while developing and Operating the lead mines in 1870 - 7 1. At first the blende was regarded as worthless, the dark variety being called black jack and lighter color resin tiff, and when either of these were struck while operating for lead, it was assumed by the miners that the lead ore had played out. Early in 1872, W. S. Mesplay recognized the material as zinc ore and shortly afterward published an article which attracted some attention to the deposits. Shortly after this Mr. Henry Blow, then superintendent of the Granby Mining and Smelting Company, made an examination of the deposits and had some samples analyzed in St. Louis. The results proved so satisfactory that he interested Mr. Lee Taylor, then foreman of the same company, and the latter purchased some black jack at from $3 to $4 per ton, selling it afterward to ore buyers who came into the camp.

Book Description
The Superfund program of the US Environmental Protection Agency (EPA) was created in the 1980s to address human-health and environmental risks posed by abandoned or uncontrolled hazardous-waste sites. Identification of Superfund sites and their remediation is an expensive multistep process. As part of this process, EPA attempts to identify parties that are responsible for the contamination and thus financially responsible for remediation. Identification of potentially responsible parties is complicated because Superfund sites can have a long history of use and involve contaminants that can have many sources. Such is often the case for mining sites that involve metal contamination; metals occur naturally in the environment, they can be contaminants in the wastes generated at or released from the sites, and they can be used in consumer products, which can degrade and release the metals back to the environment. This report examines the extent to which various sources contribute to environmental lead contamination at Superfund sites that are near lead-mining areas and focuses on sources that contribute to lead contamination at sites near the Southeast Missouri Lead Mining District. It recommends potential improvements in approaches used for assessing sources of lead contamination at or near Superfund sites.
