Metallurgy in the Middle-east. Having already mentioned that metals appeared later in the archaeological record of north-western Europe than in the south and east, and that southern metal artefacts appeared to be more advanced than northern European forms of the same age, we can now support this with earlier discoveries from the middle-east, as the following examples . In the book by Davenport et al. (Davenport et al., ), the chemistry of copper recycling in primary and secondary smelters is discussed. The Contimelt process is based on two interconnected furnaces, including a heart shaft furnace where high-grade scrap, blister copper and black copper are smelted.
Copper Sun addresses issues of the African Slave Trade, slavery in America, and freedom. Beverly Almond noted that the novel expresses “unimaginable hardship” and “starvation and disease”. Another critic claimed that the book showed themes of "pain, hope, and determination" and "human exploitation and suffering".Author: Sharon M. Draper.

Copper is one of the world's most important industrial minerals, and Africa is an important world producer. While output is traditionally dominated by Zambia, South Africa and Katanga Province in the south of the Democratic Republic of the Congo, many African nations contribute to copper production, and many African nations have undeveloped ore resources.
"Copper" doesn't make that sort of fantastic life seem effortless or easy, but it does make it seem worthwhile. Ah, and then there's "Bunny", which contains perhaps a tongue-in-cheek answer for my dog-focused wanderlust: As Copper says, "You can't force things like that, Fred.":) Either way, Copper in Africa book lightly or deeply, the book is wonderful/5(50).
Origins. Scholars previously believed that sub-Saharan Africans either did not have a period of using copper until the nineteenth century (going from the Stone Age directly into the Iron Age), or that they started smelting iron and copper at the same time (Herbert ).
Copper artifacts recovered from Nubia provide the earliest known evidence of metal smelting in sub-Saharan. The text of this book was set in Life. First Simon Pulse edition January The Library of Congress has cataloged the hardcover edition as follows: Draper, Sharon M.

Due to its excellent conducting properties, copper’s pivotal role in electronics manufacturing makes it a continually sought-after mineral – and a growing commodity. Copper is usually found in nature in association with sulfur.
Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
Copper Sun by Sharon Drapper, is an exciting, intense, and very descriptive book. The main character is a girl named Amari. She was taken from her village in Africa, after all her friends and family were killed by slave hunters/5.
